Advantages And Disadvantages Of Black Box Testing

Software testing involves execution of a software or service to check the quality of software product or service. It evaluates whether software components meet the given requirements or not. It also evaluates functionality of the software and time taken by it to run. [1] Software testing is very important for controlling the cost of the software project. Traditionally, we design and develop the program first. However, Test Driven Design (TDD) involves writing the test cases for new functions of a software first and then implementation of the code to pass these tests. This cycle of writing test cases and implementing the code is repeated till all the functionalities of the code are implemented. [2] Now, we

Integration testing can expose problems with the interfaces among program components before trouble occurs in real-world program execution. It identifies issues when two or more smaller blocks of code are combined.

Test Plan: The software is tested using two levels of testing viz. black box testing and white box testing. White box testing could be carried out in three different phases viz. unit testing system/integration testing and validation testing. • Unit Testing: Unit testing, also known as Module Testing, focuses verification efforts on the module. The module is tested separately and this is carried out at the programming stage itself.Unit Test comprises of the set of tests performed by an individual programmer before integration of the unit into the system. Unit test focuses on the smallest unit of software design- the software component or module. Using component level design, important control paths are tested to uncover errors within the boundary of the module. Unit test is white box oriented and the step can be conducted in parallel for

This chapter focuses on conducting the test case on each software unit and showing the obtained results in the form of snapshots taken where each snap describes the process being done.

code. The advantage of this type of testing is the modularity of testing returns specific results

In testing all the components are methodically verified to make sure it is error-free and make sure the requirements are met. An independent quality assurance team defines "test cases" to evaluate whether the product fully or partially satisfies the requirements in the

Software engineering comprehends several disciplines devoted to avert and remedy malfunctions and to warrant adequate behavior. Testing, the subject of this paper, is a widespread validation approach in industry, but it is still largely ad hoc, expensive, and impulsively effective. Indeed, software testing is a broad term including a diversity of activities along the development cycle and beyond, targeted at diverse objectives. Therefore,

Each component of our project will be tested multiple times, by each user. This will eliminate programming bias, and make for a more robust project.

Without clear specifications, which is the situation in many projects, test cases will be difficult to design.

Testing is a procedure of executing a project with the goal of finding a mistake.

Every tester whether consciously or unconsciously has done exploratory testing at some point in their career. Exploratory testing is about exploring the system and encouraging real-time and practical thinking of a tester.

As testing effort can’t be ignores, testing factors have to be considered. They have been addressed in ‎[54],which showed testing from two dimensions: testing level and testing

An independent quality assurance team defines "test cases" to evaluate whether the product fully or partially satisfies the requirements outlined in the first step. Three types of testing typically take place: unit testing of individual code modules; system testing of the integrated product; and acceptance testing, formally conducted by or on behalf of the customer. Defects, if found, are logged and feedback provided to the implementation team to enable correction. This is also the stage at which product documentation, such as a user manual, is prepared, reviewed and published.

In this test the pentester has no prior knowledge about the target system, extensive reconnaissance is needed as organization doesn’t provide any information about the system to be tested to the penetration tester, the penetration tester himself have to gather as much information about the target system or a network and perform the test.

Better test coverage possible by using different set of test data for the same test case.
