How to choose the best tool for your business or IT project

Whether it’s a medical test, a college entrance exam or a fitness test, testing isn’t fun.  Software testing isn’t any different – it isn’t much fun for developers who manually test newly created code for a new application their team creates or updates.  It’s easy to omit testing, but impossible to have a viable software product without it. As much as we would like developers to just get it right the first time, it isn’t going to happen, and it’s not necessarily their fault.

Developers often have little more than an agile user story to work on. Confusion and complexity can grow as different visions of the product are expressed by multiple stakeholders. Developers can’t be expected to crank out an end-product and get it right the first time.  Couple this with the constant tinkering nature of an agile-based project, and it’s easy to understand just how important continuous testing is.

Manual Testing Doesn’t Cut It Anymore

The human nature of software development dictates the need for rigorous testing.  So why would you use manual testing that incorporates the human element as well? Consider the magnitude and scope of testing required today for different applications.  Tests need to be performed for a variety of environments and different data sets. For instance, a web application must be tested in multiple platforms using varying device types, browsers and form factors.  

Automated Testing Should be the New Standard in Testing

Automated testing can simulate workloads representing anywhere from one user to thousands of users; and it goes far beyond the limitations of manual testing.  And when testing is automated it can be conducted endlessly and unattended. There’s no fatigue and the cost is minimal compared to hiring manual testers. Quality assurance automation executes the full gamut of tests you need, when you need them and with increased speed and quality.  Another great benefit? It reports the outcomes and comparative results versus previous assessments.

Different Types of QA Testing and Testing Scenarios

There are many aspects to a successful application, and therefore more than one type of testing to accommodate them.  In the end of course, it’s all about determining if the code behaves as expected.

  • Unit Test – A unit test focuses on a single unit of code such as a function in an object or module.  These tests are short and quick to run. They are especially useful when modifying existing code.
  • Test-Driven Development (TDD) – TDD is more of a development process than a testing process.  TDD breaks up the project into small repetitive development cycles. A cycle represents a minimum amount of new code that must then pass a specific test.  New code is added only if the test failed and is then retested. This process not only creates error free code, but streamlines it as well.
  • Behavior-Driven Development (BDD) – BDD focuses on the business behaviors that the code is implementing.  This is the “why” behind the code. Also referred to as acceptance testing, it helps determine if the requirements for the end user as conceived are indeed met.

Popular Automated Testing Tools Today

Selenium

First released in 2004, Selenium is one of the most popular automated software tools for browser-based web programs.  It is an open source solution and thus has no licensing costs. It accommodates multiple programming languages including Java, Python, C#, PHP, Ruby, Pert and .Net.  Tests can be conducted within the Windows, Mac or Linux operating systems and it supports multiple browsers including Firefox, IE, Chrome, Safari and Opera. With Selenium, you can be assured that your web application behaves as expected under both normal operation flows and unexpected user behaviors.  

Behat

Behat is an open source BDD testing tool for PHP. It’s used to help define how your application should behave in different scenarios.  It utilizes continuous example-based communication between developers and business stakeholders that all parties can easily understand. Every application has a list of documented actions and Behat verifies them by auto-testing them against the application itself.

BrowserStack

Created for testing mobile web applications, it is a cloud-based automated testing platform that incorporates more than 2,000 environments including various mobile devices, browsers and operating systems.  It utilizes mobile emulators of both Apple iOS and Google Android and can be utilized for continuous integration or cross-browser testing.

Cucumber

Cucumber is another BDD tool that focuses on the end-user experience and can serve as a bridge between business and technical professionals.  It supports multiple languages including Ruby, Java, Scala, Groovy and .NET. Like Behat, Cucumber is written in the Gherkin format that uses simple English and is especially user-friendly to non-programmers. It’s so user-friendly that test scripts can be written by those without any prior coding experience.

We’re only scratching the surface here because new automated testing solutions are readily being introduced and expanded upon.  There is no “one perfect” tool out there as every environment is different. When choosing an automated testing tool, consider the type of tests you’ll be conducting, the language you’re working with and ultimately the type of application you’re looking to test. Automating the QA process will soon be mainstream, so it’s best to brush up on the various tools and start thinking about how you can implement QA automation in your company.

What is QA (Quality Assurance) Automation and what are the benefits?

Remember all of the papers you had to write in school and how your teacher always told you to proof your work?  Chances are you considered it a chore taking the time to review your homework with scrutinous attention. Or maybe you were one of those that never bothered to proof it. Proofing isn’t fun for most people. Most of us enjoy creating something far more than anatomizing it for mistakes and oversights.

The same is true for writing software.  Creating code is much more satisfying than testing it in most cases.  Unfortunately, just as the failure to proof a scholarly paper rarely resulted in a top grade, creating software without ample testing throughout the coding process usually results in software that is prone to errors and bugs.  That is why quality testing is so important. The problem is that manual testing is cumbersome and time consuming. As a result, it often isn’t implemented as often as it is required. Fortunately, there is a better, easier and efficient solution available today to take the arduous task of testing off your hands.

 

QA Automation – What is it?

Many developer teams are turning to automated testing tools to perform repetitive, on-demand testing of the code they create.  Rather than depend on manual testing that is executed by scripts that are also manually created, QA Automation executes the full gamut of tests you need, when you need them. And it’s done using AI (artificial intelligence) technology.  It also reports the outcomes and comparative results versus previous assessments. QA automation allows for demand-driven testing that is consistent and reliable in an efficient cost savings manner. All browsers and user environments can be simulated with QA Automation, allowing you to test each action step throughout the program in your web-based or desktop application.  Finally, QA Automation offers a high degree of flexibility. It can be utilized as your primary testing mechanism or utilized to supplement manual testing procedures.

 

The Benefits of QA Automation

 

QA Automation Increases Efficiency

There are some things that machines do far better than humans, especially when it comes to mundane, routine, repetitive tasks.  Imagine your top programmer testing and retesting the latest code created by the team throughout the day. Is the same attention to detail made at the end of the day as at the beginning?  Machines are ideal for testing code. They can do so a million times without any deviation to routine or neglect of detail. They are the ideal mechanism to test code.

Not only does QA Automation improve the efficiency of your testing processes, it does the same for your code development progression as well.  The perpetual ritual of testing and retesting serves as a constant interruption to the task that your developers do best – write code. Why distract them from what they do best when a machine can perform the testing process more reliably.  Any disruption to the creation process creates a bottleneck. QA automation eliminates those bottlenecks, freeing up your staff to focus on creating rather than proofing.

 

Improved Accuracy and Reliability

The pace of application development today is relentless, and is only increasing with time.  This unremitting pace also increases the necessity for testing. If a machine doesn’t care how many tests it runs, then your developers can increase the test schedule as well, integrating it into their routines so that it becomes a natural component of the build process.  Outcomes and outputs are no longer predicted, but confirmed. Because the recurring testing processes are consistent, greater accuracy is achieved, leading to greater reliability. All of this translates into more success whenever code is released to production. The business is happier when the cycle time to make code live is shorter.

 

QA Automation saves and money

The old cliché, “time is money” rings particularly true, especially when it comes to labor intensive practices such as code development.  QA Automation allows your developers to stay focused on creating code that adds direct value to the business rather than spending valuable time creating manual test scripts.  While you can utilize dedicated software testers, they cannot replicate the inexorable pace of automated testing. Money invested in automated testing is recovered quickly due to the drastic reduction or even possible elimination of manual testing hours.

Technology professionals know all too well that not every test is going to be a success, and with fewer tests runs, the more time it usually takes to remediate the bugs discovered in each manual assessment.  By increasing your test frequency using automation, you shorten the period in between those tests, making remediation necessities more manageable. With QA Automation, test frequency doesn’t directly relate to added costs.

Automating the QA process is a win-win for everyone involved in the software development process.  Your developers can stay focused on the task of creating and updating applications that generate value for your company.  The software they create is more reliable, and consistency means end users enjoy a better experience. All of this translates into lower costs, which makes executives and business leaders happy as well.
