The app was featured in some of the most-read periodicals and has since helped over 50,000 girls access healthcare.

13. What Are Some Of The Test Cases That Don’t Have To Be Automated?

As a QA automation engineer, I know when I should perform automated testing or not to save the team resources and time. I do not always automate test cases that are rarely executed or can be quickly executed manually. I don’t also automate test cases that stretch to exploratory and usability tests. Even though there are several reasons for the last mentioned test cases, it is mainly to prevent misuse of time and resources. I will also do the same in this organization unless directed otherwise.

14. Walk Us Through How You Decide On The Tools Used For Automation Testing

My first considerations when picking the right tools for automation are the requirements, as they help me with the right testing scenarios to automate. Once I know all the requirements, I extensively research the tools that will meet the project requirements. However, I also consider whether the budget can cover the necessary tools, resources, and skilled personnel. I would then compare all the needed tools to determine if they can do the work without overstretching the provided budget. I am glad that I always end up with the right tools.

15. How Do You Normally Select Test Cases For Automation?

A QA automation engineer should always determine the test case’s execution frequency and whether it is critical for business features and functions. Therefore, I usually determine whether the test case is necessary and whether it is more of an end-to-end scenario. I then consider the automation needs when setting the execution frequency and monitor different defects once the test run begins. I finally analyze the results within the given time frame at the end of the automation test, ensuring that I save time that would have been spent on manual execution.

16. Do You Know Selenium?

I haven’t worked with Selenium, but I know quite a lot about it. I learned it a while back, even though I mostly use the scripting language it supports, such as PHP and Java. I know that Selenium does an excellent job in functional and regression testing. I can assure you that I will do a good job when called upon to use this framework, even though I haven’t had a chance to work with it on projects.

17. What Are The Advantages Of Automation Testing?

As a QA automation engineer, I can attest to the advantages of automation testing as it primarily determines how automation impacts a company. The results obtained from the test can be used to delegate resources to other departments, lower the company’s operating costs, and save on labor, allowing members of a particular team to engage in other roles. Automation also saves time and times resources. I am confident that I will help the company enjoy all these benefits by performing automation tests.

18. How Many Cases Can You Automate In A Day?

I don’t have a particular value since I have once spent the whole day automating a single test whose impact was more prominent than 50 smaller tests. The number of tests I run in a day depends on how complex the test cases are. I can automate seven to ten test cases in a day if they are less complex, but one or two for more complex cases. I also prefer breaking down challenging test cases into smaller elements, such as calculation and output verification, helping me achieve proper organization. Therefore, the number of tests in a day depends on their complexity.

19. Can You Mention The Different Types Of Automation Frameworks

There are five automation frameworks that one can use. The linear framework is the easiest as it entails writing a single program without any modularity in sequential steps, whereas the data-driven framework runs a similar set of operations on various data sets stored in different files, which are excel sheets in most cases. The hybrid framework combines the linear and data-driven frameworks, making it partly data and keyword-driven. Lastly, the BHT framework allows programs to be broken down into business components and used with either of the frameworks mentioned above.

20. What Do You Understand By Automation Testing?

Automation testing is done using automation processes and testing tools. In automation testing, the automation engineers develop automated tests processes for various systems and tools. These tests ensure that a given software or technological product meets all the requirements to benefit the end-user. It, therefore, confirms that the given product does whatever it is destined to. Therefore, the test cases check for defects, bugs, and any issue that needs attention.

21. How Would You Convince A Client That They Need Automation Testing?

The best way to convince someone to try automation testing is to mention its benefits. Automation serves teams that do not have the time or resources to test software manually, therefore helping them save on both. It is a quicker and more efficient method of testing products. I would also tell the client that automation testing allows frequent testing, which enhances functionality given that software development requires several tests or the same one repeatedly. Lastly, I would let the client know that automation testing allows continuous development.

22. What Are Some Of The Tests That Should Be Automated?

Any QA automation engineer will tell you that not all tests can be automated and, therefore, one needs to choose wisely. Some of the tests that qualify to be automated include high-risk tests, tests that would waste time when tested manually, tests that are impossible to perform manually, repetitive and monotonous tests, tests that can fail due to human error, extensive tests, and those that need to run on several hardware or software platforms.

23. Differentiate Unit Tests From Smoke Tests

Smoke tests are generally used to confirm the stability of a product. It tells whether a given product is stable or not. This product is often sent back to developers, who run further tests to identify the cause if found to be unstable. On the other hand, unit tests assess every component of a given software or product. It thoroughly tests these elements before the final version is released. Developers usually write unit tests, a requirement phased out by automation testing.

24. Can You Walk Us Through The Automation Testing Process

The automation testing process has different stages. First, the QA automation engineer must select the tool to utilize depending on the test goals and needs. Luckily, there are several tools and web apps in the market. The next step is to establish the scope of automation, which is the area test to be automated. This is where the QA automation engineer prepares the test data and the proper testing environment before moving to the planning stage, which focuses on creating a testing strategy. We then have the execution stage, where one runs the test and performs API testing. The last stage is the ongoing maintenance stage necessary for running future tests.

25. What Is Your Biggest Attribute That Qualifies You For This Job?

I have several attributes that qualify me for this job. However, I believe that my attention to detail and proficiency in different tools and coding make me a great QA automation engineer. I always know what to look for when performing automation tests and rerun tests for better results. I have worked on many complex projects owing to these attributes, which makes me optimistic that I will do a good job here if given a chance.
