HP offers Testing-as-a-Service solution

Yvette Francino Yvette Francino Profile: Yvette Francino

With the onset of cloud computing and utility-based pricing, “as-a-service” solutions are becoming more popular. HP has recently added Testing-as-a-Service as an outsourcing alternative for complex testing needs.

For the past 10 years or so, HP has provided Managed Testing Services, which offer a variety of testing services including staff augmentation or full-testing-service solutions, with pricing based on people-hours. The difference with the TaaS solution is that the pricing is “consumption-based.”

I spoke with Paul Ashwood of HP Enterprise Services, who explained:

The “as-a-service” model is all about consumption of service, which means you need to have a lot of repeatable activity. And when you’re doing the development of application, there’s a lot of new stuff there that you can’t really price. Where we apply TaaS is more around applications that are already in production where you need to do regression testing. Regression testing is well served by test automation. Test automation and test regression is all very repeatable.

The services that HP is offering in their TaaS Solution include:

1) Accelerated Test Service – Regression test automation. Pricing is based on test cases rather than the cost of people. The service also includes the maintenance and execution of the automated test cases.

2) Performance Test Service – Pricing is based on Performance Test Units (PTUs.) PTU values are based on things like the number of the steps in the test case or the number of virtual users, etc. Clients pay for what they use, rather than having to purchase the tools themselves. 

3) Application Security Testing – Leverage WebInspect to for penetration testing and the Fortify tool to do code scanning. The price is per assessment or Website. The client doesn’t need to pay for the tools.

4) SAP Test Service – Accelerated Test and Performance Test specifically for SAP. HP has built out common business scenarios and common test cases for SAP.

The advantage to the client is that they are paying for what they use rather than paying for people or tools who may not be needed during certain downtime periods.

This type of solution is typically used post-production for mission-critical applications. As Ashwood points out, the solution does not depend on a relationship with specific people, and the success of their model includes having “test factories” in various countries and the ability to move resources to where the need is. 

What is key to these models is the concept of a factory approach. So rather than the client saying, ‘I’m buying 20 of your test automation engineers for the next two years,’ instead what they’re buying is 20,000 executions of automated test cases over the next two years. So the people are not tied to a client anymore.

Obviously, this is a different approach than the tight coupling of developers and testers that is encouraged in Agile development models. Ashwood agrees that this model is not conducive to new development work, but, again, it is cost-effective for specialty testing of mission-critical applications.

Rona Shuchat, Director of Application Outsourcing Services at WW IDC Services Research Group say has this to say about TaaS solutions:

The reality around testing as a service or on demand testing as some refer to it, is that different vendors are positioning different offerings under this term “TaaS” or “On Demand Testing”. Companies like SOASTA, for example, are pushing a cloud based test service, also on demand, that is focused on performance testing and load testing – where multiple load generators can be combined to enable scalability out to hundreds or thousands of virtual users. SOASTA promotes its real-time BI engine to capture and report out on performance metrics. This service can be purchased for x hours, or monthly or annually.

A company like Skytap is also offering cloud based on demand test lab environments, and are positioning their cloud service as on demand virtual data centers that can drive parallel dev/test requirements or positioning as a test environment on demand to support unit testing, system testing, UAT or performance testing. We also see prepackaged domain solutions being offered under the term “TaaS” – for SAP, or other ERP solutions (e.g. Infosys, HP, etc. ). Perfecto Mobile offers automated testing solutions for mobile devices, enabling mobile developers to test mobile apps and content on a range of real devices over the web and so on.

Security scanning on both sides of the firewall

Yvette Francino Yvette Francino Profile: Yvette Francino

Recently, WhiteHat Security announced Sentinel PL (PreLaunch), a service for website security testing done before an application is released to production.

Senior Analyst from the 451 Group Wendy Nather says:

With Sentinel PL, WhiteHat is addressing the growing need to move security testing farther upstream in the software development lifecycle. Catching problems earlier means lower remediation costs and better-informed risk management in the release process.

It’s undisputed that the earlier in the software development cycle that defects are found, the easier and cheaper it is to fix them. However, security testing is often only done post-release, if at all. While there is still the need to test security post-release, it makes sense to test whatever can be tested pre-release as well.

The other day I spoke with WhiteHat CSO Bill Pennington and product specialist Ravi Iver about their service and the announcement. Up until now their service began once the code was complete and deployed in a production environment. They heard that their customers felt their service could be improved if some testing could be done in the pre-production environment.

I asked about some of the differences in testing in pre-production versus post-production.

Pennington answered that there were several tradeoffs that needed to be made for production testing to ensure availability, stability, performance and security.

[In production] we’re pretty low and slow. We generate less overhead than a standard Web browser. All of our tests are non-destructive, so when your looking for things like cross-site scripting (XSS), there’s two ways to do it. You can inject live JavaScript into the site. If you do that, then if they do end up having a vulnerability, you can drop in pop-up windows all over their site, which is not going to do much for confidence or their consumers, and it’s going to lead the bad guys on the path to directly where that vulnerability is. So the approach we take is to drop in pseudocode for those types of tests, chunks of things that are omnipotent and non-executable, that when we look at them we know a vulnerability is there, but no one else will.

We’ll be able to be much more agressive [earlier in the SDLC.] We’ll be able to inject live JavaScript. We’ll be able to do live SQL injection, we’ll be able to automatically test every form because we’re in a different environment than we are in production.

The challenges of Agile transition: Stop and regroup

Yvette Francino Yvette Francino Profile: Yvette Francino

The other day I attended Rally Software’s Agile Cafe in Boulder, giving me the opportunity to hear more stories of “real world” Agile. I had just attended the Boulder Agile Software Meetup group the week before and heard about some of the obstacles to Agile acceptance. Two of the speakers at the Agile Cafe were real world success stories, but both of them did experience obstacles with their transitions.

Bill Holst, President & Principal Consulting Software Engineer at Prescient Software, talked about two projects done for Colorado Springs Utilities, one done with waterfall and one with Agile. Though the Agile project was successful, it started with a lot of problems. A key factor in its success was that the team stopped halfway through and the customer group, in this case field engineers, reworked the requirements.

The second presenter was Adam Woods, Director of Product Development at StoneRiver. Woods described a phased transition to Agile for a major development effort. One of the biggest obstacles encountered was the lack of buy-in and understanding of Agile principles from executives, project leaders and delivery teams. Woods, too, attributes a key to the eventual success to taking the time to stop and regroup when necessary. As the team did this, they inspected and adapted, going back to basic principles. Recognizing the importance of engagement from the product owners, they changed their model, and eventually gained the acceptance needed from all stakeholders.

Jean Tabaka, author of Collaboration Explained, followed up with a keynote, describing important factors for success in Agile transition. I had a chance to catch up with Tabaka after the presentation for a quick summary.

The flexibility of automation in ALM

Yvette Francino Yvette Francino Profile: Yvette Francino

This month on SearchSoftwareQuality.com we are talking about automation in ALM. As I read through the various content, I’m recognizing what a vast amount of automation is involved in software development. In the context of software testing, I used to think of “automation skills” as skills with record and playback tools, such as HP’s QuickTestPro or maybe the popular open source tool, Selenium. However, there are many more types of automation and a variety of tasks that automation can perform.

Not only is automation used for multiple tasks, but often a specific type of automation can serve multiple purposes.

As Agile Testing co-author Lisa Crispin writes in Automated test scripts: The Smartphones of testing:

Automated test scripts also serve multiple purposes. We write tests up front so that we know what code to write and when it is finished. Creating the tests is a team activity which enhances collaboration and communication. Automated test scripts provide up-to-date documentation about how the system behaves. Automating our regression tests not only provides quick feedback as we check in code changes, keeping regression failures out of production, it frees time for all-important exploratory testing to find out whether the software delivers the expected business value.

In the end, that’s what we all want isn’t it? We want to automate the tedious, repetitive tasks, and to use our minds for the critical thinking.

Automation in ALM

Yvette Francino Yvette Francino Profile: Yvette Francino

It’s a new month and with that, we have a new theme at SearchSoftwareQuality.com: Automation in ALM. Throughout the lifecycle, there are ways that project teams are automating their processes and their work to provide efficiency so they can focus on those tasks that require critical thinking.

I’m excited about our lineup for the month, starting with these three pieces we published this week about automation in ALM:

Test automation: When, how and how much
Test automation has often been touted as an important part of an organization’s quality strategy. However, it’s not a silver bullet. In this tip, consultant David Johnson describes important considerations in determining when to invest in test automation, how to implement the program, and how much of your application space should be automated.
 
UI Testing: Automated and Exploratory
Should user interface (UI) testing be automated or exploratory? In this tip, SSQ contributor Chris McMahon answers that both automated and exploratory testing can be used for UI testing, and what is most effective is using them together. McMahon explains when each type of testing is appropriate and how used together, they can complement one another to provide the most comprehensive UI test coverage.

Six Tips for Selecting Automated Test Tools for Agile Development
Software consultant Nari Kannan describes the differences between agile application lifecycle management tools and traditional lifecycle management software. Agile ALM tools are more tightly integrated, easier to use, support distributed teams and seamlessly integrate many of the traditional lifecycle management functions.

Transitioning to Agile: Learn from the skeptics

Yvette Francino Yvette Francino Profile: Yvette Francino

Promoting Agile internally was the topic at last week’s Boulder Agile Software Meetup Group.

[kml_flashembed movie="http://www.youtube.com/v/5gK5Nq40n3Y" width="425" height="350" wmode="transparent" /]

In this video, Matt Weir speaks about transitioning to Agile and how he learned the most from the skeptics. He found that by listening and working together to address concerns, the skeptics became his best allies in the transition.

uTest releases new apps for the iPhone and iPad

Yvette Francino Yvette Francino Profile: Yvette Francino

Crowdsource test group uTest announced January 18th the release of a new mobile application for their customers and 30,000+ tester community. The application allows testers to use their iPhone or iPad to enter bugs, communicate with the uTest community and customers, accept invitations to projects, upload screenshots or videos and view their earnings.

As a member of the uTest community, I went ahead and downloaded the app to my iPhone, installed it, and in just a few short minutes was able to access my uTest account from my iPhone.

The new iOS apps were tested, of course, by the uTest community, the very group who had been asking for these apps. In this case, they had a vested interest in the application being user-friendly, as they were both testers and soon-to-be users.

Having just spoken with Arxan about the importance of security on mobile devices, I was particularly interested in security and testing on mobile applications. I spoke with uTest’s Matt Johnston, who said:

[We needed to consider both] security of customer’s data and tester’s data. We took every available precaution in working with our outside provider on this app. And of course, uTest tested the app to make sure it held up. So absolutely security was baked in from the beginning, from conception, through development, through testing. The other [security consideration] is IP protection. Again, we made sure the IP was secure for uTest, but more importantly, we made sure it’s a secure and private experience for testers and customers.

I wondered if uTest was thinking of entering the tools market, but Johnston said that at this time the tools are focused on catering to the needs of the testers and customers of uTest, allowing them to work more productively by tying into the uTest platform. Though the primary objective has always been to address the needs of the uTest testers and customers, an added benefit has been the interest and addition of new testers for uTest’s ever-expanding tester community. Johnston explained:

It’s only been available for a couple of days, but we’re seeing upwards of 20 new testers a day who are signing up through the iPhone and iPad apps, finding it in the iTunes store or reading about it in an article and coming to us through those applications as opposed to signing up through the Web interface. So we’ve been very pleasantly surprised that it’s been such a good thing for tester recruiting so quickly.

In less than two days, it’s been downloaded more than 500 times (with an even split between iPhone and iPad users), which is quite high for a specialized B2B application. For those 500 downloads, the app store has shown a rating of 4.5 out of 5 stars. Johnston attributes this to the “in the wild” testing that was performed vs. lab testing. He elaborated:

In doing the four test cycles, we tested on four separate continents with a team varying between 10 and 20 people, and getting a lot of OS coverage and carrier coverage. It’s been battle tested as much as it can be, ahead of launch.

How does the uTest community like the new app? All reviews on the iPhone app were rated 4 or 5 stars with only positive comments. In looking at the comments on uTest’s blog, again, they were unanimously positive. If there was any dissatisfaction, it may be from those using other mobile platforms who are wondering when their favorite platform will be supported. However, even those who are without an iPhone or iPad are positive, sending kudos to uTest for their hard work.

How secure are your mobile and embedded applications?

Yvette Francino Yvette Francino Profile: Yvette Francino

A wide array of security tools are available to handle threats that are prevalent over the desktop and server-centric code running in untrusted environments. But what about the newer mobile devices? Applications are being downloaded by the billions by consumers and these applications may be at risk from hackers who are able to pirate or reverse engineer your applications. Are tools available to protect your IP?

Last week, I spoke with Vince Arneja, vice president of product management at Arxan Technologies, about their product launch of EnsureIT for Apple iOS. This product is designed to protect applications running on Apple’s iPhone or iPad against reverse-engineering or tampering for unauthorized access, piracy and
insertion of exploits. He explained:

Our technology introduces itself right into the build process. Typically a customer will use our type of product to obfuscate the code that is written by the developer, so that code is inherently harder for a hacker to understand the logic of and subsequently be able to manipulate.

I asked whether obfuscation had the potential for causing performance problems.

Arneja answered:

Absolutely, it can. A lot of that is controllable by introducing it into the build process. The technology can have an adverse affect on performance, but it’s all managable. There’s a balancing act that needs to be assessed for any aspect of security. In the case of the application, [you’d ask the question] how much security do I want to introduce and still balance the performance that my customer expects? The tuning that can be accomplished is all part of what we call, ‘a guard specification style.’

Arneja went on to explain the configurations that can be done to create the appropriate balance of security and performance.

Curious about obfuscation tools and whether or not their use would grow as a means to protect mobile and embedded applications, I spoke with some analysts in the industry. In Application security hardening for mobile and embedded software, Bob Walder, Research Director at Gartner, said of code obfuscation:

Code obfuscation is the more widely adopted and more-mature method of protecting applications, but estimated adoption rates are still in the high single digits, because most organizations are unaware of its benefits until they directly experience the theft of IP or an attack from an application compromise. Furthermore, for application protection techniques that rely on the insertion of code, development organizations may be reluctant to allow the injection of new code into an application from a source other than a developer.

What are your thoughts?

Agile ALM with Michael Hüttermann

Yvette Francino Yvette Francino Profile: Yvette Francino

At SearchSoftwareQuality.com, we have a lot of content about “agility” and about “application lifecycle management” (ALM). But often these terms are used in many different contexts. Some people refer to almost any tool that manages part of the development lifecycle as an “ALM tool,” and “agility” seems to be the buzzword of the year, referring to almost any process that promotes collaboration. What does “Agile ALM” really mean?

Well, I got the chance to talk to the expert, author of Agile ALM, Michael Hüttermann. Hüttermann’s book is jam-packed with information about building agility into your development lifecycle. Reading this, decision makers will be able to see the difference between the vendors who play buzzword bingo and those who really implement what’s most important in an ALM tool. I found his book a virtual goldmine of information.

In Agile ALM: Interview with author Michael Hüttermann – Part 1, I queried Hüttermann about software configuration management (SCM), “lightweight” tools, and the importance of integration of tools that manage different aspects of the lifecycle.

In Agile ALM tools: Q&A with author Michael Hüttermann – Part 2, we talk about attributes of agile ALM tools, automation, and tradeoffs between flexibility, configurability and complexity in tool sets.

Stay tuned as we have further interviews with Hüttermann and continue to explore this very timely topic.

Agile ALM by Michael Hüttermann is available through the MEAP (Manning Early Access Program) at Manning.com. Compliments of Manning.com, there is a 41% discount on the MEAP, ebook and pbook of Agile ALM. Please use promotional code: agilealm41 in the Promotional Code Box at Manning.com.
