Software Testing Interview Questions

Introduction

Software testing is defined as a technique to check whether the final software or the product matches the expected requirements of the customer and to ensure that the product is defect-free. It uses manual or automated tools to evaluate the properties of interest in the software. Software testing aims at identifying errors or any missing requirement in contrast to actual requirements specified by the customer. It can be stated that software testing means verification of the application under test. It is important to perform software testing so that any bugs or errors in the software can be identified and rectified before the final product is delivered.

When preparing for a software testing interview, one should go through the previously asked software testing interview questions as many questions are repeated. This blog will answer some of the important software testing interview questions that an interviewer is likelier to ask.

Top Software Testing Interview Questions

Some of the important software testing interview questions are:

1. What type of input is required from the end-user in order to begin proper testing?

The end-user is one of the most important people as they are the ones who have to use the product and have a keen interest in the product. The below diagram shows all are the inputs that are essential from the end-user


2. Briefly describe the workbench concept.

Workbench is described as a way of documenting how a task is to be performed. It is often referred to as phases, steps, and tasks. 

Mainly there are five tasks of a workbench, which are:

  • Input
  • Execute
  • Check
  • Production output
  • Rework


3. What do you understand by defect Cascading?

When an interviewer asks the above question as a part of software testing interview questions, the answer should be that defect cascading is a defect that is caused by another defect. In other words, when a defect triggers another defect. This happens when a defect is present in any stage but does not get identified and, as a result, gets passed to other phases without getting noticed. This increases the number of defects.

While answering such types of questions when asked in a software testing interview questions, try giving examples like:

If we are to design the login module of a webpage.

  • In Phase 1: We will be designing the Register User Module for Login, and we need to make sure that the mobile number is mandatory, but we intentionally leave it blank to create a bug that gets unnoticed.
  • In Phase 2: We will be designing the login form having a username as well as a password, the password is the OTP which will be sent to the User's registered mobile number entered before.

Now, as the Register Module has a bug that mobile number can be left blank, which will lead to Login failure or some sort of system error or crash if the null mobile number is not handled. Such a thing is known as defect cascading.


4. Name the different strategies that can be used to rollout to end-user.

The different strategies that should be mentioned when asked as a part of software testing interview questions are:

  • Pilot
  • Gradual Implementation
  • Phased implementation
  • Parallel implementation


5. Explain the process through which we can find a broken link in a page using Selenium WebDriver.

This is a tricky question that is present in almost every set of software testing interview questions. In such a question, the interviewer can provide you with 20 links on a web page and asks you to verify which of them are working and which aren't. As we need to verify whether a link is working, the main workaround is to send HTTP requests to all of the links on the web page and then analyze the response. When we use a driver.get() method to navigate a URL, it responds with a status of 200-OK. This depicts that the particular link is working fine, whereas any other status indicates that the link is broken.

To perform the above task, all we have to do is use the anchor tags <a> to determine the different links on the web page, that is, for every <a> tag, we use the href attribute to obtain the hyperlinks and then analyze the response we receive when the driver.get() method is used.


6. Which technique should we use in the script "if there is neither frame id nor frame name"?

Frame by index should be used if neither the frame id nor the frame name is available. For instance, if there are 4 frames on a web page and none of them have a frame name and frame id, we can still select those frames by using the zero-based frame index attribute, that is, the first frame would be at index 0, the second frame at index 1 and so on.


7. Is it possible to take a screenshot in Selenium WebDriver? If yes, then how?

It is very commonly asked in software testing interview questions, the answer to this shouled be Yes, by using the TakeScreenshot function. The TakeScreenshot function allows the user to take a screenshot, and the getScreenshotAs() function helps the user to save the screenshot.

Example, File ssFile = ((TakeScreenshot)driver).getScreenshotAs(outputType.FILE);


8. What process will be followed if you have to log in to any site if it shows an authentication popup for username and password?

In such cases where there is a popup for logging in, we have to use the explicit command and verify whether there is an alert actually present or not. The code below will help you understand the use of the explicit wait command.

WebDriverWait wait = new WebDriverWait(driver, 10);
Alert alert = wait.until(ExpectedConditions.alertIsPresent());
alert.authenticateUsing(new UserAndPassword(**username**,**password**)); 


9. How can we skip a method or a code block in TestNG?

Such short questions, when asked in any software testing interview questions should be answered by stating that if we want to skip a method or a code block in TestNG er can simply set the 'enable' parameter in the test annotation to false: @Test(enabled=false)


10. Can you describe what the below code snippet indicates?

WebElement example = driver.findElement(By.xpath("//*[]contains(text(),'content')));


The above snippet defines a variable example of WebElement type and uses an XPath search to initialize it with reference to an element that contains the text value "content"


11. What is the key difference between regression testing and retesting?

The key difference between regression testing and retesting is one of the interviewer's favorite questions, which is very common in all software testing interview questions. Regression testing is done to make sure that the new changes or modifications to a module do not have any adverse effects on the previous releases. Whereas the retesting is just running the same tests again. 


12. What is the key difference between system testing and integration testing?

The main difference between system testing and integration testing is that in system testing, the entire system as a whole is tested or checked, whereas, in integrated testing, only the interaction between the individual modules is tested.


13. What is the difference between QA and testing?

The purpose of performing QA and testing are very different as the purpose of QA is to prevent errors in the application, whereas the purpose of testing is to find errors.


14. What is meant by bug severity and bug priority?

Bug severity refers to the level of impact that a bug has on the application, while bug priority refers to the level of urgency in the need for a fix.


15. What are the steps involved in performing sanity testing?

Sanity testing is similar to smoke testing, it is the initial testing of an application done to ensure that it's functioning at the most basic level and is stable enough to continue more detailed testing.
