SOFTWARE TESTING
software testing
Verification is the process, to ensure that whether we are building the product right i.e., to verify the requirements which we have and to verify whether we are developing the product accordingly or not. Activities involved here are Inspections, Reviews, Walk-throughs
software testing
Validation is the process, whether we are building the right product i.e., to validate the product which we have developed is right or not.
Dynamic Testing
Dynamic testing involves the execution of code. It validates the output with the expected outcome
White Box Testing
White Box Testing is also called as Glass Box, Clear Box, and Structural Testing. It is based on applications internal code structure. In white-box testing, an internal perspective of the system, as well as programming skills, are used to design test cases
Box Testing
Black Box Testing is a software testing method in which testers evaluate the functionality of the software under test without looking at the internal code structure. This can be applied to every level of software testing such as Unit, Integration, System and Acceptance Testing. Click here for more details.
Grey Box Testing
Grey box is the combination of both White Box and Black Box Testing. The tester who works on this type of testing needs to have access to design documents. This helps to create better test cases in this process.
Positive and Negative Testing
Positive Testing: It is to determine what system supposed to do. It helps to check whether the application is justifying the requirements or not.
Negative Testing: It is to determine what system not supposed to do. It helps to find the defects from the software.
Test Strategy
Test Strategy is a high-level document (static document) and usually developed by the project manager. It is a document that captures the approach on how we go about testing the product and achieve the goals. It is normally derived from the Business Requirement Specification (BRS). Documents like Test Plan are prepared by keeping this document as a base.
Test Suite
Test Suite is a collection of test cases. The test cases which are intended to test an application.
Test Scenario
Test Scenario gives the idea of what we have to test. Test Scenario is like a high-level test case.
Test Case
Test cases are the set of positive and negative executable steps of a test scenario which has a set of pre-conditions, test data, expected result, post-conditions and actual results.
Test Data
Test data is the data that is used by the testers to run the test cases. Whilst running the test cases, testers need to enter some input data. To do so, testers prepare test data.
For example, To test a basic login functionality having a user id, password fields. We need to enter some data in the user id and password fields. So we need to collect some test data.
Test Closure
Test Closure is the note prepared before test team formally completes the testing process. This note contains the total no. of test cases, total no. of test cases executed, total no. of defects found, total no. of defects fixed, total no. of bugs not fixed, total no of bugs rejected etc.,
Test Report
A test report is a document that provides an overview of testing objectives, activities, and results. It is necessary to summarize testing results and compare them against expectations. It helps us determine if the product is ready for release or not. Additionally, it allows us to see the current status of the project and assess the quality of the product
What are the levels of testing?
In software testing, there are four testing levels.
- Unit Testing or component level testing
- Integration Testing
- System Testing
- Acceptance Testing Unit Testing Unit Testing is also called Module Testing or Component Testing. It is done to check whether the individual unit or module of the source code is working properly. It is done by the developers in the developer’s environment. Integration Testing Integration Testing is the process of testing the interface between the two software units. Integration testing is done in three ways. Big Bang Approach, Top-Down Approach, Bottom-Up Approach. System Testing Testing the fully integrated application to evaluate the system’s compliance with its specified requirements is called System Testing AKA End to End testing. Verifying the completed system to ensure that the application works as intended
