 Software testing level There are 4 basic levels of testing, including: 1. Unit Test Concept: Unit testing is a type of software testing in which individual units/components of the software, such as functions, classes, and methods, are tested. Unit testing is conducted during the application development process. Errors at this level are usually fixed immediately after they are found, without being logged and managed like other test levels. Typically, programmers are the ones who perform testing at this level. Purpose: Isolate Components : Separate each component to verify and demonstrate that they accurately fulfill the functional requirements specified.  Early Bug Fixing : Errors are rectified early in the software development cycle, thereby saving time and cost in error correction.  Increased Code Reusability : The source code can be reused more frequently.  Enhanced Confidence in Modifications or Maintenance : Increases confidence in making changes or maintaining ...

  Testing Methods   Software testing methods are conducted by testers with the aim of ensuring that all features of the system operate correctly according to the requirements of the customer or end users. There are three basic software testing methods: white-box testing, black-box testing, and gray-box testing. In the previous session, we learned about the white-box testing method. Now it's time to move on to the other two testing methods. 1. Black-box testing What is the black-box testing? Black-box testing is a software testing method that focuses on testing the functionality of an application without needing to know its internal structure or source code. In this approach, testers are only concerned with the inputs and outputs of the system to determine whether the functionality operates correctly, without considering how it works internally. Black-box testing is similar to inspecting a black box, where you only observe the input and output transformations without knowi...

Testing Methods   Software testing methods are conducted by testers with the aim of ensuring that all features of the system operate correctly according to the requirements of the customer or end users. There are three basic software testing methods: white-box testing, black-box testing, and gray-box testing. Overview of white-box testing What is the white-box testing? White-box testing, also known as clear-box testing, glass-box testing, or structural testing, is a software testing technique where the internal workings of an application's code are examined. In this method, testers have access to the source code and use their understanding of its logic to design test cases. The goal is to ensure that all paths and conditions within the code are tested thoroughly, helping to uncover any hidden bugs or vulnerabilities. Types of white-box testing Types of white-box testing include: Statement Coverage Testing: Checks each line of source code to ensure that all lines have been exec...

The 7 principles of testing Software testing is an essential part of the software development process, ensuring that the final product functions correctly and efficiently, meeting all requirements and customer expectations. To conduct software testing effectively and save time and effort in identifying and addressing errors, you can adhere to the following seven fundamental principles of testing. 1. Testing shows the presence of defects Testing proves that the product has defects but cannot prove that the product is defect-free. This means that there will always be defects undetected in the software, even if no defects are found, it does not mean that the software is defect-free. 2. Exhaustive testing is impossible  It is very difficult to test all modules as well as features, combined with all inputs and outputs of the entire system throughout the testing process. Instead of attempting to test everything, identify the importance and priority to test the necessary cases or those wi...
