Re-testing occurs after a defect has been fixed and returned to the test team for verification.  Unless the fix is not confirmed, re-tests are conducted only once.  If the fix is confirmed, ...

REGRESSION TESTING  :If we get any code / Functaionilty change in the project , then we need to test it whether this change will effect the Exixting fuctonality or code.RE -TESTING :Some times wh...

TEST CASE PREPARATION- Study and learn about requirements and specfications- Ask questions to fill gaps in knowledge- Create test cases- Map requirements to test cases- Prioritize test cases- Conduct ...

Test case can be written with the help of only with SRS 

Priority denotes sequence of the defect in which they are going to Rectified.

Severity describes the seriousness of the defect.

Severity means: How the Bug Effects On the Application

Priority means : How soon Bug needs to fix

Testing is the verification of the customer requirments and black box testing are test that only knows the input and the output of the test, but not knowing the internal mechanism of the test.

This is a big area with a lot of methods and esp. if you want if from the basics.. The best thing is to attend a course or read a book about it. I recommend "Foundations of Software Testing" by Dorothy Graham.

matrices plural of matrix.

Traceability Matrix is a document which consists information for tracing back for the reference in case of any confusable and questionable situation.

Error: Error is a mistake in code

Defect: Due to error in code test engineers are getting mismatches in the application build are defect

Bug: Defects are assigned to developer to be solved
Failure: Not meeting the reliability of the product

Bug: any mistake which can impact the expected functionality of system
Defect: When bug is identified by tester then it becomes defect

Scalability testing lets you ensure that your web application is scalable, that is, it can handle an increased workload with added resources and determine whether it best scales up, by upgrading the s...

Scalability Testing, part of the battery of non-functional tests, is the testing of a software application for measuring its capability to scale up or scale out [1]- in terms of any of its non-functio...

Quality of the software is what the client pays for. It means it should perform the intended functions without any major flaws.

Quality Software Deliverable means:
1. Delieverable meets User/Customer Requirements.
2. Reasonably Bug-Free Software.
3. Delivered within defined Timeline & Budget.
4. Easily Maintainable. Also, Less Post Release Maintainence Activity, thus reducing Cost.

Its Quality. Testing is a Quality Control (QC) activity. Software testing is the process of finding the defects so as to improve the quality of software. It doesnt mean that the software is 100% defect free but the quality will be high after validating when compared before testing.

Purpose for Software Testing:1. To ensure whether the software Build is as per User Requirements/.2. To ensure reasonably Bug free Software, to uncover bugs withing software, if any.3. To improve qual...

The difference between postive and negative testing is this:Positive testing attempts to verify that an application behaves as intended (satisfies requirements).Negative testing attempts to revea...

Positive Testing : Testing the application with valid data

Negative testing: Testing the application with invalid data
