This is not a good approach to save sometime by minimal testing at the unit phase. In case, you skip the unit testing phase then big errors can come in the project. If big errors come in project then there will be more cost required to fix things at later stage. It has been also seen that many errors are found in the Beta phase of software testing that is also very irritating. If you want to fix errors after detection at Beta stage then it will cost very high.
There are three types of testing that are directly concerned with unit testing namely integration testing, system testing and acceptance testing. Some features of the unit testing are as listed below:
- If bug is detected early then it will be fixed early too.
- If detected then fixation of the error will be also quite easy. If same bug is detected at later stage then regression testing will become complicated.
- It becomes quite easy to connect small parts of well tested codes. If there will be no error at any stage then after connecting codes there will be no chance of error.
Now you would have understood why unit testing is important and it should be done carefully. Reputed companies all across the world go very conscious for the stage of unit testing.
