It is impossible to automate everything. Achieving 100% automation is difficult because there are situations where a registration page has a captcha or some test case that we don’t perform very often. Automation will not add value by automating such tests.

CAPTCHA stands for Fully Automated Public Turing Test to distinguish between computers and humans. The reason for creating a captcha is to control bots.

If someone is able to automate the captcha, it means that the captcha is not able to distinguish between a computer and a human. So the idea behind captcha fails.

To automate an application that uses captcha, you need to consult with your development team to provide a solution.

Automation Testing Tools

Fixing the captcha in your test environment helps you automate the captcha by assigning a specific value as the captcha in each run.

12. What kind of tests do you have automated? Our main focus is to automate test cases to perform regression testing, smoke testing and sanity testing. Sometimes based on project schedules and testing time, we focus on end-to-end testing.

Automation testers need to understand what actually needs to be automated. Identifying the appropriate test cases for automation plays a critical role in the success of automation testing.

14. How many test cases do you automate per day? It depends on the complexity and length of the test case. I automated 2-5 test scenarios per day when complexity was limited. Sometimes there is only 1 or less test per day when the complexity is high.

15. What kind of test cases would you choose to automate? Before automatically taking test cases, I check if the application is stable. So based on this, if the AUT changes frequently and I rarely run it and only run it once, I won’t choose a test case. Also, I don’t automate when I do usability and exploratory testing.

16. Name some popular automation tools you know? Some popular automation tools include Selenium WebDriver, QTP/UFT, JMeter, LoadRunner, Ranorex, etc.

17. How do you choose an automation tool? Choosing an automation tool is essential for test automation. There are many automation testing tools in the market. The following are some of the factors involved in choosing an automation tool.

18. What is a frame? A framework defines a set of rules or best practices that we can systematically follow to achieve desired results.

19. Why Framework? In an automation testing project, we perform different tasks using different types of files. We use a framework to organize and manage all files and complete all tasks in a systematic way.

We can do automation testing without a framework. A framework is a set of rules or best practices that we can systematically follow to achieve desired results. If we understand automation tools we can do automation testing without framework but if we create and follow framework it will help in many ways.

21. Have you developed any framework? If you are a beginner: No, I haven’t had a chance to build a frame. I used an already available frame. If you are an experienced tester: Yes, I have built frameworks (or) No, but I am involved in building frameworks.

JVM stands for Java Virtual Machine. It translates and executes Java bytecode. It is the module that transforms Java into a “portable language” (ie, write once, run anywhere). However, each platform has its own implementation of the JVM ie. Windows, Linux, macOS, etc. have a special version of the JVM to run bytecode.

and are OS-level environment variables. Path specifies the location where the system can look for executable (.exe) files, and classpath specifies the location of Java class files.

No, constructors in Java should have the same name as their clusters. If the name is different, it will behave like a normal method.

When you define methods, you pass variables that you refer to as parameters. And when you call these methods and pass values ​​to variables, they are used as arguments.

It is certainly possible to have many main methods in different categories. When you start the program, you need to provide the name of the startup class to run. The JVM then only looks for the main method in the class you provided the name for. So you won’t notice any conflicts with multiple classes that have


Pass by reference indicates passing the address itself instead of passing the value. Pass by value means to pass a copy of the value.

The Java compiler generates bytecode for all Java code and converts it to class files. Bytecode is platform-independent and requires a platform-specific JVM to run.

Yes, we can compile, but it won’t run. The “main” method acts as an initializer function for a Java class and is called by the JVM to run the application.

Call . It will print 0. This indicates that the array is empty. If it were null, it would throw a NullPointerException when calling .

If the object no longer belongs to a variable, Java automatically reclaims the memory. This process is known as garbage collection. You can use the method to call it directly.
