Q1. Software Testing Question
Explain STLC.
Ans. 
STLC (Software Testing Life Cycle) is a fundamental part of SDLC which is used to test software and ensure that the
quality standards are met. It generally involves both verification activities and validation activities. In this, different
activities are executed in a specific order throughout the software testing process. There are basically six different
phases in STLC. They are as follows :

1) Requirement Analysis
2) Tes...read more

Q2. Software Testing Question
Write the difference between Test Stub and Test Driver.
Ans. 
Test driver and test stub, both are types of test harness that are used to provide a simulation environment for testing
a module or component. They both are dummy modules specially created for test purposes.

Test stubs: Test stubs are used in a top-down testing approach and allow testing of the upper levels of the code when
the lower levels of the code are not developed yet. It is used as ‘called programs’ when subprogram...read more

Q3. Software Testing Question
What do you mean by Data flow testing?
Ans. 
Data flow testing is a type of structural testing that is used to analyze the flow of data in the program. In this, a
programmer can perform various tests on data values and variables. Using this testing, one can determine the
variables that are used at every stage of the program’s control flow. It helps us in the following ways:

1) Eliminate or remove variables that are never used after being declared
2) Pinpoint variable...read more

Q4. Software Testing Question
What is boundary value analysis?
Ans. 
In software, many errors occur near the edges of the range of the data values. For example, when the programmer
uses the greater-than operator (>) instead of the greater-than-or-equal-to (>=) operator, it causes the off-by-one
indexing error.

Typically, developers miss these boundary cases because they follow a happy path when developing and testing.
Boundary value analysis helps to discover the errors caused by extr...read more

Q5. Automation Testing Question
What are the different parts of a test automation framework?
Ans. 
A test automation framework makes it easy to perform automation testing for your software. Here are some
components of a test automation framework.

1) Test Data Management :
i) A big problem in automation testing is generating the test data. A good test automation framework makes it easy to
build test data for the application under test.


2) Testing Libraries :

Q6. Automation Testing Question
What are some of the best practices in test automation?
Ans. 
Here are some of the best practices a software development and the testing team should use to ensure quality software.

1) Decide what to automate :
i) It’s not possible or practical to automate certain tests, such as usability, accessibility, exploratory testing, or non-
repetitive test cases that frequently change.


2) Assign test cases based on skill and experience :
i) When dividing test cases, take into account the skill...read more

Q7. Automation Testing Question
How do you automate the testing of CAPTCHA?
Ans. 
It’s not possible to automate the testing of CAPTCHA. That is the goal behind any good CAPTCHA strategy. By
definition, a computer can’t automate it. If it could, then it’s not a good challenge that you can use in your application.

However, if you need to test an application that uses CAPTCHA, you have to work with the development team to
build a workaround or a back door that allows the automated test to bypass the CAPTC...read more

Explain what are the JUnits annotation linked with Selenium?
Ans. 
The JUnits annotation linked with Selenium are :

1) @Before public void method() – It will perform the method () before each test, this method can prepare the test
2) @Test public void method() – Annotations @Test identifies that this method is a test method environment
3) @After public void method() - To execute a method before this annotation is used, test method must start with

Q6. Cucumber Question
How can you run a selected test from a group of tests in Cucumber?
Ans. 
1) We may execute a single test from a set of tests in the Cucumber framework using the tags idea. 

2) This is found in the TestRunner file's @CucumberOptions section. With the use of the @t keyword, we may tag a scenario in the feature file. 

3) A scenario can have one or more tags within the feature file. We can separate test scenarios with the
assistance of tagging. 

4) We must pass the value within the t...read more

Q7. Cucumber Question
What is grouping in the context of Cucumber?
Ans. 
Cucumber is unconcerned about the names of your step definition files or the order in which you place them. Instead
of maintaining all steps in a single file, we can create steps.rb file for each major action/feature. This is referred to as
grouping.

Q8. BDD Question
Explain briefly how Behavioral Driven Development(BDD) works?
Ans. 
There are majorly three steps in the working of BDD. They are as follows:-

1) Behaviour Description: We list down the features of our application first in the feature file.

2) Making the Step Definition file: The mapping between each step of the scenario defined in the feature file and a
code of the function to be executed is stored in the steps definition file.

3) Testing and running: We run the test cases to check if we ...read more

Q2. Difference between rank dense rank
Ans. 
Rank assigns unique numbers to each row, while dense rank does not leave gaps between ranks.
• Rank assigns unique numbers to each row based on the order specified.

• Dense rank also assigns unique numbers to each row, but does not leave gaps between ranks.

• For example, if we have scores of 90, 85, 85, 80, rank would be 1, 2, 2, 4 and dense rank would be 1, 2, 2, 3.
