Bosch Global Software Technologies Senior Test Engineer Interview Questions, Process, and Tips

Q1. What is unit testing
Ans. 
Unit testing is a software testing method where individual units or components of a software are tested in isolation.
• Unit testing helps in identifying bugs early in the development process

• It ensures that each unit of code is working as expected

• Unit tests are usually automated and run frequently during development

• Examples of unit testing frameworks include JUnit for Java, NUnit for .NET, and pytest for Python

Q2. How do you perform unit testing
Ans. 
Unit testing is performed by writing test cases for individual units or components of the software to ensure they work as expected.
• Write test cases for each unit or component of the software

• Execute the test cases to verify the functionality of the unit

• Check for expected outcomes and compare with actual results

• Use testing frameworks like JUnit, NUnit, or PyTest

• Automate unit tests to run them regularly during development

In this round , I was first asked some basic questions revolving around Software Testing in general and then when I told
the interviewer that I was more inclined towards Automation Testing he started asking me asking me questions around
that. In the end, the interviewer also asked me some questions related to SQL and DBMS.

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
What is the importance of agile testing?
Ans. 
Agile testing is basically a software testing process that uses agile methodologies i.e., follow test-first design
paradigm. It evaluates the software from the customer's point of view. It does not require any development team to
complete coding for starting QA, instead of testing and coding can go hand in hand. Features are tested as they are
developed. Some of its advantages include :

1) Boosts the performance as it allo...read more

Q3. Automation Testing Question
What’s the difference between manual testing and automated testing?
Ans. 
1) Manual Testing - A human executes the test cases one by one, without any software assistance.
Automated Testing -Tests are executed by a testing tool or framework, without human assistance.

2) Manual Testing - Useful for non-repeatable tests that involve human ingenuity, participation, and domain
experience.
Automated Testing - Useful for repeatable tests where the software feature under test doesn’t change frequently.

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 skills...read more

There are 7 aggregate functions in SQL :

1) AVG(): Returns the average value from specified columns.
2) COUNT(): Returns number of table rows.
3) MAX(): Returns the largest value among the records.
4) MIN(): Returns smallest value among the records.
5) SUM(): Returns the sum of specified column values.
6) FIRST()...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
test@Before

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 tags argument to exe...read more
