what is the difference between test coverage and fault coverage?
240497
Test coverage generally refers to how thorough the test program is compared against requirements. ... Fault coverage generally refers to how thorough functional test is. It is expressed in terms of percentage of nodes in the circuit exercised during functional test.

Substantive testing is very different from testing controls. Substantive tests verify whether information is correct, whereas control tests determine whether the information is managed under a system that promotes correctness. Some level of substantive testing is required regardless of the results of control testing.

“A mistake in code is called Error . ” Error found by tester is called defect , Defect accepted by development team is called Bug . And build does not meet the requirements then it is Failure .

Difference between defect, error, bug, failure and fault: “A mistake in coding is called error ,error found by tester is called defect, defect accepted by development team then it is called bug ,build does not meet the requirements then it Is failure.”

Black Box testing has the main goal to test the behavior of the software whereas White Box testing has the main goal to test the internal operation of the system. Black Box testing is focused on external or end-user perspective whereas White Box testing is focused on code structure, conditions, paths and branches.

A Bug is the result of a coding Error and A Defect is a deviation from the Requirements. A defect does not necessarily mean there is a bug in the code, it could be a function that was not implemented but defined in the requirements of the software.

“A mistake in coding is called Error, error found by tester is called Defect, defect accepted by development team then it is called Bug, build does not meet the requirements then it Is Failure.” ... In other words Defect is the difference between expected and actual result in the context of testing.

In TDD (Test Driven Development), the test is written to check the implementation of functionality, but as the code evolves, tests can give false results. BDD (Behavior Driven Development) is also a test-first approach, but differs by testing the actual behavior of the system from the end users perspective.

Performance testing is not a type of automation testing where test scripts are created using a tool and automated test runs are scheduled. In functional or automation testing, test coverage becomes a very important factor, whereas, in performance testing, test accuracy becomes essential.

verification is concerned with whether the system is well-engineered, error-free, and so on. Verification will help to determine whether the software is of high quality. Testing refers to the process of executing an application or program with the intent of detecting potential software bugs.

What's the difference? Positive test cases ensure that users can perform appropriate actions when using valid data. Negative test cases are performed to try to “break” the software by performing invalid (or unacceptable) actions, or by using invalid data. Let's take a straightforward example.

Whereas QA is proactive, QC is reactive. QC detects bugs by inspecting and testing the product. ... It is the process of executing a system in order to detect bugs in the product so that they get fixed. Testing is an integral part of QC as it helps demonstrate that the product runs the way it is expected and designed for.

A pretest loop tests its condition before each iteration. A posttest loop tests its condition after each iteration. A posttest loop will always execute at least once.

The difference between Fault and Weakness. When used as nouns, fault means a defect, whereas weakness means the condition of being weak. Fault is also verb with the meaning: to criticize, blame or find fault with something or someone.

Whereas QA is proactive, QC is reactive. ... Testing is a subset of QC. It is the process of executing a system in order to detect bugs in the product so that they get fixed. Testing is an integral part of QC as it helps demonstrate that the product runs the way it is expected and designed for.

In system testing, whole software or application is tested at a time. In end-to-end testing, behavioral flow of the software is tested. System testing only tests the specific software system. It tests the software system and the connected systems both.
