Expleo Solutions Software Tester Interview Questions and Answers

Testing techniques are methods used to verify and validate software applications to ensure they meet requirements and function correctly.

• Black box testing: Testing the functionality of a software application without knowledge of its internal code.

• White box testing: Testing the internal logic and structure of a software application.

• Regression testing: Re-running tests on previously tested software to ensure that new cha...read more

Regression is a software testing technique used to ensure that new code changes do not negatively impact existing functionality.

• Regression testing involves re-running previously executed test cases to verify that new code changes have not introduced any new bugs or issues.

• It helps ensure that the software continues to function correctly after modifications.

• Regression testing can be automated to save time and effort.

• Exa...read more

Testing Life Cycle includes planning, designing, executing and reporting. Bug Life Cycle includes reporting, assigning, fixing and verifying.

• Testing Life Cycle involves planning, designing, executing and reporting of tests.

• Bug Life Cycle involves reporting, assigning, fixing and verifying bugs.

• Testing Life Cycle starts with requirement analysis and ends with test closure.

Severity is the impact of a bug on the system while priority is the urgency of fixing it.

• Severity is the measure of how much a bug affects the system's functionality or performance.

• Priority is the measure of how urgently a bug needs to be fixed.

• A high severity bug may not have a high priority if it does not affect critical functionality.

• A low severity bug may have a high priority if it affects critical functionality.

• Bo...read more

Challenges faced during testing phase

• Lack of clear requirements

• Limited access to test environment

• Time constraints

• Difficulty in reproducing bugs

• Integration issues with third-party systems

• Lack of proper documentation

• Testing on multiple platforms and devices

• Dealing with unexpected errors

STLC stands for Software Testing Life Cycle, which is a systematic approach to testing software.

• STLC involves different phases such as requirement analysis, test planning, test design, test execution, and test closure.

• Each phase has its own set of activities and deliverables.

• STLC ensures that the software is thoroughly tested and meets the quality standards before release.

Some common testing tools include Selenium, JIRA, Postman, and TestRail.

• Selenium - for automated testing of web applications

• JIRA - for bug tracking and project management

• Postman - for API testing

• TestRail - for test case management and reporting

Regression testing is the process of retesting a software application to ensure that new code changes have not adversely affected existing functionality.

• Regression testing is performed after code changes to verify that the existing features still work correctly.

• It helps in identifying any defects introduced by new code changes.

• Automated testing tools are often used for regression testing to save time and effort.

• Example...read more

Smoke test is a preliminary test to check if the basic functionalities of a software application are working correctly.

• Smoke test is a subset of regression testing.

• It is usually performed after a build is deployed to ensure the critical functionalities are working.

• Smoke test is not exhaustive and focuses on the most important features of the application.

• It helps in identifying major issues early in the development cycl...read more
