21) What is thread testing
A thread testing is a top-down testing, where the progressive integration of components follows the implementation of subsets of the requirements, as opposed to the integration of components by successively lower levels.
12) What is Agile testing and what is the importance of Agile testing
Agile testing is software testing, is testing using Agile Methodology. The importance of this testing is that, unlike normal testing process, this testing does not wait for the development team to complete the coding first and then doing testing. The coding and testing both goes simultaneously. It requires continuous customer interaction.
5) What is bug leakage and bug release
Bug release is when software or an application is handed over to the testing team knowing that the defect is present in a release. During this the priority and severity of bug is low, as bug can be removed before the final handover. Bug leakage is something, when the bug is discovered by the end users or customer, and not detected by the testing team while testing the software.
3) What is the difference between build and release
Build: It is a number given to Installable software that is given to the testing team by the development team. Release: It is a number given to Installable software that is handed over to the customer by the tester or developer.
20) What is CRUD testing and how to test CRUD
CRUD stands for Create, Read, Update and Delete. CRUD testing can be done using SQL statements.
6) What is data driven testing
Data driven testing is an automation testing framework, which tests the different input values on the AUT. These values are read directly from the data files. The data files may include csv files, excel files, data pools and many more.
29) What is a Test Metric in software testing and what information does it contains
In software testing, Test Metric is referred to the standard of test measurement. They are the statistics narrating the structure or content of a testing. It contains information like Total test Test run Test passed Test failed Tests deferred Test passed the first time.
22) What is configuration management
It is a process to control and document any changes made during the life of a project. Release control, Change control and Revision control are the important aspects of configuration management.
23) What is Ad Hoc testing
It is a testing phase where the tester tries to break the system by randomly trying the system's functionality. It can include negative testing as well.
17) Explain stress testing, load testing and volume testing
Load Testing: Testing an application under heavy but expected load is known as Load Testing. Here, the load refers to the large volume of users, messages, requests, data, etc. Stress Testing: When the load placed on the system is raised or accelerated beyond the normal range then it is known as Stress Testing. Volume Testing: The process of checking the system, whether the system can handle the required amounts of data, user requests, etc. is known as Volume Testing.
36) Explain what is MR and what information does MR consists of
MR stands for Modification Request also referred as Defect report. It is written for reporting errors/problems/suggestions in the software.
4) What are the automation challenges that SQA(Software Quality Assurance) team faces while testing
Mastering the automation tool Reusability of Automation script Adaptability of test case for automation Automating complex test cases
7) Explain the steps for Bug Cycle
Once the bug is identified by the tester, it is assigned to the development manager in open status If the bug is a valid defect the development team will fix it. If it is not a valid defect, the defect will be ignored and marked as rejected The next step will be to check whether it is in scope. If the bug is not the part of the current release then the defects are postponed If the defect or bug is raised earlier then the tester will assign a DUPLICATE status When bug is assigned to developer to fix, it will be given a IN-PROGRESS status Once the defect is repaired, the status will change to FIXED at the end the tester will give CLOSED status if it passes the final test
35) Explain what should your QA documents include
QA testing document should include List the number of defects detected as per severity level Explain each requirement or business function in detail Inspection reports Configurations Test plans and test cases Bug reports User manuals Prepare separate reports for managers and users.
31) Explain what is the difference between Regression testing and Retesting
Retesting is carried out to check the defects fixes, while regression testing is performed to check whether the defect fix have any impact on other functionality.
16) What are the tools used by a tester while testing
Selenium Firebug OpenSTA WinSCP YSlow for FireBug Web Developer toolbar for firebox. Above are just sample tools. The tools a Tester may vary with his/her project.
18) What are the five common solutions for software developments problems
Setting up the requirements criteria, the requirements of a software should be complete, clear and agreed by all The next thing is the realistic schedule like time for planning , designing, testing, fixing bugs and re-testing Adequate testing, start the testing immediately after one or more modules development. Use rapid prototype during design phase so that it can be easy for customers to find what to expect Use of group communication tools.
37) What does the software QA document should include
Software QA document should include Specifications Designs Business rules Configurations Code changes Test plans Test cases Bug reports User manuals, etc.
32) List out the software quality practices through the software development cycle
Software quality practices includes Review the requirements before starting the development phase Code Review Write comprehensive test cases Session based testing Risk based testing Prioritize bug based on usage Form a dedicated security and performance testing team Run a regression cycle Perform sanity tests on production Simulate customer accounts on production Include software QA Test Reports
13) What is Test case
Test case is a specific condition to check against the Application Under Test. It has information of test steps, prerequisites, test environment, and outputs.
11) What are the contents of test plans and test cases
