San Diego Quality Meetup 5/4/2016

I have long hoped that San Diego testing community would develop a user group/meetup. My recruiter, Jon Barton of TEKSystems, started a meetup group. I attended a meeting in April. Then I volunteered to speak at a future meeting. That future meeting was last night.

I am hopeful for the future of software testing in San Diego if they group becomes a place for people to step out of their circle of comfort, to mentor each other, to learn and grow.

Test Automation Curriculum

Two things happened to me lately. First, I was trying to find a career tester in the San Diego area that knows at least a little bit about automated testing. It isn’t going well. I’ve reviewed a lot of resumes. all the submitters are career manual testers.

Surely somebody sometime must have wondered if they need to learn more about automation. Elisabeth Hendrickson once asked Do Testers Have to Write Code? They did a survey to figure out what companies were looking for from tester skills. In our case, we aren’t looking for somebody to write the test code, but to write and review the cucumber scenarios. Just the same, even on a light desire level, I was disappointed.

Second, a younger person asked me what he should learn in test automation last week. I had already been contemplating writing this curriculum, so I was resolved to do it. Srini, here it is.

Other people who don’t work with LAMPs, such as .Net environments etc. will probably not appreciate this list. Make your own list on your own blog and put the link in a comment here. I don’t begrudge anybody doing something else. I just don’t want to go there.

I created this curriculum for testers learning test automation. While some addresses how and why, most of the list is about tools that can help create a full solution. Anyway, here is my list in priority order:

  • An open source tool such as Watir-Webdriver or Selenium/Java – do not mess around with the QTP and TestComplete. The cargo cults that buy those tools will expect “anybody can automate”.  With open source tools, you can download your own learning playground and incorporate that with the other products.
    • Learn how to create page objects. Even if you take advantage of a library like WatirMark or Page-Objects, you will have to do some tailoring yourself. I have been working with Selenium/Java so I am developing my skills on that combination now. Either way, you need to know how to work on that in an efficient way. In fact, you can address a lot of the entries in here just be using Cheezy’s book Cucumbers and Cheese (well worth the $15). I swear that I do not get a dime from it or Cheezy’s work, it’s just such a big benefit for anybody learning that I cannot miss the chance to say how good it is.
    • An open source framework such as Cucumber, Cucumber-jvm, or RSpec.
  • Github and Git – there are other good source control tools out there, including subversion. Git is easy to use locally for managing your own practice code. It’s easy go get copies of other people’s public projects onto your own system (how did they do that?). CodeSchool has a free course on git. There is also a nice paper on the differences between git/mercurial and subversion so you can understand the differences.
  • Ant and Maven if you use Java. Most of what I learned was through osmosis, but being able to shoehorn cucumber into your project is good to know.
  • Jenkins or Hudson, CruiseControl, or some other open source continuous integration tool. If you ever work at a place that will be introducing automated testing for the first time, this is great to know how to set it up.
  • Performance testing in JMeter – I think you can find a ruby alternative (BlitzIO or Grinder) but you don’t really need this tool to be in a ruby language. The importance is to learn the different kinds of testing you find under this umbrella (incorrectly) called Performance Testing. The other important skill is creating the right monitors so you can discover where things are bottled up.
  • Owasp‘s ZAProxy – learn how to capture the http calls between your browser or simulator and the server under test. You will learn a lot there. While you are there, download the GoatWeb project where you can learn about security vulnerabilities through practice.
  • Monitoring tools (Splunk or Graylog2) – One way to find the errors that are occurring on the system under test is through logging. Those are deleted nearly every time the server is redeployed. You can monitor those logs and server performance much better through a monitoring server.
  • A true startup is probably not going to hire a newb unless they are cost-control-centered. But if you find you get there are there is no issue tracking, it would be good to know how to set up issue tracking and integrate to your version control and continuous integration server. I’ve tried RedMine and it was fine.

If you see that you think should be on the list that is not there, please add a comment.

What Everybody Should Know About Buying Test Automation Tools

Vendor Tools Fail for Developing Software

Discussed recently on my Twitter  feed was question about test jobs and the required skills. Somebody pointed out that many ads list selenium or QTP. Why both? The person asking told me at one time he had used both and knew both. I think he asked the question because he knew the products were quite different. Or maybe because the hiring manager did not seem to know about that difference.

I have used many products, vendor, open source, and home-grown for automating tests through the years. A vendor test tool just means that somebody is selling it for money.  In this case, lots of money.

They are all  for the purpose of running tests (typically functional tests). However, they are so different that people tend to join a camp and stick with it.  What’s your preference?

My favorite is open source tools (in general), but I am good with whatever tool gets the job done. Productivity is the most important to me. Maybe that is why open source is my favorite. Let me share some of my analysis on the vendor products. Keep in mind the context of my primary job is testing software that is under development. My analysis is greatly influenced by what I need to do.

Source Control

Vendor tools supply source control systems with their tools. I have seen this with QTP and Test Partner. So you have to install a database server or test management system to connect to (and the test management system stores it’s data in a database like SQL Server or Oracle).

Is that good or bad? When the tools were formed, it was probably good – good because testers weren’t used to fooling with source control systems like svn, git, or perforce; good because crazy people like me could ruin hours, days, or weeks of work with a screwed up search/replace-all action; good because they captured so much data when they recorded scripts. Are they still good to have? At this point,  I say no. They are not needed because people are using the dev source control system anyways – two systems are not better than one. They aren’t needed because they editing/using the tests depend on an active connection – people want a copy on their system and only sync when necessary.


Vendor tools number one strength is the plug-ins they build to tackle automated testing on wicked technologies like Flex. And it’s not new. WinRunner and Astra QuickTest were some of the first products to support testing web technologies. This versatility helps sell the vendor tools.

Unfortunately for them, many of the technologies they sell plugins for will come-and-go. I believe that HTML5 will push those EOL’s a little faster. In the meantime, open source alternatives are available for widely used languages like java, ruby, and perl.

Integrations with other tools

Automated test tools integrate with other products like test management systems, defect tracking systems, and requirements tracking systems. There was a time that vendor-sold tools were the most integrated products. Why? Because they often owned all of the tools. They were able to integrate the products through internal knowledge sharing by teams. The integrations, unfortunately, were often based on technologies like dynamic data exchange (DDE) and object linking & embedding (OLE). That was good once upon a time, as were video cassette recorders.

Today products can integrate through the native language when they are libraries. When they are not, RESTful web services are convenient and reliable. I have seen substantial efforts to update vendor products to use modern integration technologies but they are often handcuffed by their customer-bases’ reliance on current product models.

Visually Oriented/Helpful

The first automated tests I ever wrote were tests that I didn’t write. I used a process that has been around since Microsoft Test (later Visual Test, later Rational Visual Test) called Record & Play. Was that helpful? As a learning experience, it was helpful. The tests created by the recordings were not helpful. The recordings are not helpful for long because they do not follow Good Practices for Automating Functional Tests. Even the tool vendors will concede that the recordings must be edited to minimize maintenance in the future.

Try creating the scripts without the recorder. I haven’t used some of the major vendor tools, but I know with QTP that I wasn’t able to build the script with the recorded objects. The objects are the early friend. They help you get the script created without knowing anything. Eventually, though, you will need to fix all those tests because the software under test has changed. How many tests are depending on that object? Are they multiple objects that look similar? Can you effectively minimize the number of objects during your development iterations as the product under test changes? All these concerns make me want to skip the object repositories. I want to know what is going into my tests, what is coming out, and be able to see what is happening behind the scenes.


Vendor tools sell themselves well with customer support. Actually, they sell the customer support. The revenue from maintenance is usually higher than the revenue from sales. They can do this because the customer needs the fixes and improvements from the version they purchased. There is absolutely no DIY for those tools. The good part is that you do not have to fix it, but that bad side if you can’t.

There are forums for discussing issues in open source tools & libraries. The product authors and other volunteers answer questions about the products to help both experienced and new users, including providing direct access to defect tracking systems. When the cause of issues are found, the plans for release are posted and the user can resolve the issue themselves in their own library code base.

Foot Print

For software, the foot print is the total impact on a computer – space required to install on the hard disk drive, RAM used to run it (both edit and execution modes), licensing connections, integration connections, database connections, and cost to license.

The foot print affects every person that will use the automated test scripts to learn about the product under test. Today’s development methodologies are designed to reduce the gap in time from when a defect is introduced to when it is fixed. Build it regularly and test it regularly using continuous integration systems (e.g. Hudson). Let the failing tests be run on the developers system that checked the defective code in to the repository. Foot print matters.

The vendor tools are bulky and expensive to say the least.  QTP 11 requires a minimum of 1gb storage and 1gb RAM. A use can get by without any connections (to database or to QC) but not a team. I haven’t been able to find the exact cost, but I am seeing ~$6,000 on my Google searches.

Test Complete 8 requires a minimum of 700mb storage and 256mb RAM.  It’s $1,000 for an individual node-lock license and $4,500 for an enterprise floating license (prices in between for mixes of those two).

Telerik Test Studio requires 500mb storage and 500mb RAM. Each of  of those three leading vendor tools require Windows XP, Windows Vista, or Windows 7. Their most popular package (some tools but missing most) is $1,300 while the complete package for one user is $7,334.

Compare those minimum requirements to Selenium test automation tools. Selenium is 31mb (server and java client), runs on Windows, Mac OS X, Linux, and Solaris. Ruby, the core language for the Watir and Watir-Webdriver libraries, supports Windows, Mac OS X, Linux, Solaris, and (I have never heard of) OpenIndiana. Ruby is 275mb (measure for v1.93) with Watir-Webdriver requiring an additional 18b. They are both free, the support is free, and the maintenance is $0.  That’s a huge difference.


For automating tests on software development projects, I believe the vendor tools are inferior to the open source tools. It seems counter-intuitive – why wouldn’t the vendor tools adopt the capabilities of the open source tools?

First, they can’t because of the install-base requires them to remain the same. These products have been selling for up to and even more than a decade. People, departments, companies rely on the tools they have invested so much time into. Regardless of whether they tests are brittle or not, they cannot choose (or allow the vendor to choose) a radical change to how their systems are built. So instead they build new features and modules to sell while the core remains the same.

Second, they do not want to because their target is vast market of uninformed manual testers and managers. I have walked through vendor showcases at StarWest. They have interfaces that are way sexier than VIM. The trials seem so easy. “Come on in here, automate a test – everybody is doing it!” So you do it and it works beautifully. Of course you don’t have to run that test on your system, against your software, or maintain it. Their core target usually knows none of the good automation practices they should follow. But their companies take their advice and pony up the money.

As I mentioned before, the context of my job plays a significant role in my analysis above. If I were choosing a product for testing in an IT department (which is service-oriented), my priorities would change, and the tools I favored may change. I do not dislike vendors. I do not think they mean harm, in fact they provide utility.
