💡 Consider the following three laws before writing Unit Test :

1- You may not write production code until you have written a failing unit test.

2- You may not write more of a unit test than is sufficient to fail, and not com-piling is failing.

3- You may not write more production code than is sufficient to pass the currently failing test.

Test code is just as important as production code❗️

It is not a second-class citizen .

It requires thought, design, and care .

It must be kept as clean as production code .

#CleanCode #UnitTest

What makes a clean test❓

Three things : Readability, readability, and readability.

Read-ability is perhaps even more important in unit tests than it is in production code .

What makes tests readable ❔

The same thing that makes all code readable :
clarity, simplicity & density of expression .
