Every professional associated with the web development sector is aware of the meticulous efforts to write and run a code. However, many code lines succumb to bugs and result in application failure. Code testing is an integral part of the software development process that focuses on the smallest parts of the application called units. Although code testing does not add anything new to the code except validating the existing code, it is extremely useful. Many programmers have begun to run automated tests to detect errors and run the code smoothly. In her article for Zeomag, Prachi Manchanda talks about the importance of code testing and how you can enhance their quality.
Understanding Code Testing and Enhancing Its Implementation
Tips to Implement Code Testing Effectively
Here is a list that will help you enhance test-driven development:
- Prepare a plan.
- Lessen the operational complications.
- Test frequently.
- Introduce naming conventions.
- Learn about its applications.
When to Write Code Testing Functions
Many web developers mention that it is better to write test-driven development guidelines before you start working on the actual code. However, some developers prefer writing test functions and the code simultaneously. It gives them an idea of what they need to check at the end of the program.
Checking the Quality of Test Functions
Code coverage is one of the standard parameters to assess the quality of your test functions. Code coverage gives you a percentage of development code your test function can cover. Most web developers assert that a test function is acceptable if its required code coverage is more than 90%.
How Effective Is Code Coverage for Code Testing
Manchanda states that although many companies use code coverage to check the quality of test functions, it is not highly effective. For instance, if you are testing a function to find the maximum in an array, you will find the operationality of the function. It will give you 100% code coverage because it does not check the instances where the array is out of bounds. Therefore, it is crucial to check your code manually.
