Is Lcsaj a black box testing?

LCSAJ testing is a white-box testing methodology used to determine the code coverage, i.e., what percentage of the code is executed with the existing test cases. It helps in designing new test cases, which can increase the coverage of the code under test.

What are the techniques of white box testing?

White-box test design techniques include the following code coverage criteria:

• Control flow testing.
• Data flow testing.
• Branch testing.
• Statement coverage.
• Decision coverage.
• Modified condition/decision coverage.
• Prime path testing.
• Path testing.

Why is white box testing used?

White box testing is an approach that allows testers to inspect and verify the inner workings of a software system—its code, infrastructure, and integrations with external systems.

What are the two types of path testing?

Path Testing Techniques:

• Control Flow Graph: The program is converted into control flow graph by representing the code into nodes and edges.
• Decision to Decision path: The control flow graph can be broken into various Decision to Decision paths and then collapsed into individual nodes.
• Independent paths:

What is alpha test and beta test?

Alpha Testing is done within the organization, while Beta Testing is done in the user’s environment. During Alpha Testing only functionality and usability are tested, while during Beta Testing usability, functionality, security, and reliability are tested to the same depth.

Why smoke testing is done?

Smoke testing is carried out in the initial stages of the software development life cycle (SDLC). It ensures that all the core functionalities of the program are working seamlessly and cohesively. Smoke testing is executed before any functional tests are done.

How long does a smoke test take?

You need to think about 30 minutes or 60 minutes as the duration of the Smoke Tests. You can be sure that something is not right. Your test cases aren’t simple enough, or the code is of poor quality.

Is path testing a black box testing?

Statement Coverage, Branch coverage, and Path coverage are White Box testing technique. Statement Coverage validates whether every line of the code is executed at least once. Path coverage method tests all the paths of the program.

Why is path testing needed?

Every software program has multiple entry and exit points in the source code. Path testing verifies these points in the source code to ensure there are no bugs encountered in the execution of processes through a program sequence.

Does 100% path coverage imply 100% branch coverage?

For a test set to achieve 100% branch coverage, every branching point in the code must have been taken in each direction, at least once. The archetypical example, showing that 100% statement coverage does not imply 100% branch coverage, was already given by Alexey Frunze.

How is path coverage calculated?

To calculate Statement Coverage, find out the shortest number of paths following which all the nodes will be covered. Here by traversing through path 1A-2C-3D-E-4G-5H all the nodes are covered. So by traveling through only one path all the nodes 12345 are covered, so the Statement coverage in this case is 1.

What is the purpose of alpha testing?

Alpha testing is the initial phase of validating whether a new product will perform as expected. Alpha tests are carried out early in the development process by internal staff and are followed up with beta tests, in which a sampling of the intended audience actually tries the product out.

What are the types of smoke testing?

There are three types of Smoke testing namely: – Manual Method, Automation Method and Hybrid Method. The manual method is the most commonly used smoke testing method under which the smoke test cases are tested manually for the fresh build and the newly added features.
