Getting To Know More About Test Driven Development (TDD):
Definition, Types Of Testing, And Advantages Of TDD
The readiness of an application or website is the responsibility of a developer to ensure it. So the term Test Driven Development (TDD) emerged which is useful for ensuring that your application/website is free from errors or Bug Free. Test Driven Development (TDD) is a development that refers to testing before carrying out the coding process.
TDD combines the advantages of coding and testing in its implementation, this process is also carried out to ensure that our application is running according to requirements and is able to handle various cases or situations.
Testing Categories and Types of Testing
- When you finish working on a feature, the question that often arises is “what is the benchmark for this feature to be finished or not?” the answer is if it passes testing from these two test categories:
- Does the software meet the specified requirements?
- Does the software still run in various unexpected cases?
- The two testing categories above only involve all components, there are still types of testing that are more intended to test code components in various scopes. In general, the types of testing based on their scope are divided into three, namely:
- Unit testing: testing whether the function or class in the code runs properly
- Integration testing: testing whether a feature runs properly when combined with other parts of the application / website
- Acceptance testing: testing whether the application / website can be used by users without experiencing bugs or errors
- Ideally, an application / website needs to be tested based on the three scopes above, each scope also contains functional and non-functional tests.
- Differences between Test-Driven Development (TDD) and Regular Development
- In general, testing is done after the feature is finished, this process occurs in regular development. While in the TDD process, testing is done before creating the feature. Advantages of Test-driven Development
Of course, TDD has advantages over the usual development process, including:
More objective output targets
- Makes developer work more effective because the developer’s target is only to write code that passes the test, rather than writing code that meets features A, B, C, and so on
- Developer performance is more monitored and good for measuring team performance
- Room for code development or refactoring is more visible
- But keep in mind that TDD does not promise that applications / websites can be completed faster, because TDD only promises a more objective and transparent development process.
