Developers often write a unit test with only the goal to get as close to 100 LC as they can. I always learned that doing maximum code coverage with unit tests is good.100 test coverage is great, but it doesnt magically mean your software is perfect.

On WPF-related things and other frameworks that are very difficult to test, we get much lower coverage (barely 70).

Even with 100 of coverage, your code is not perfect. Take a look at this method (in fact it depends on which type of coverage you are talking about - branch coverage, line coverage)Most developers who write unit tests shoot for the mid to high 90s. So is 100 code coverage worth pursuing?Unit testing (especially the test first approach) is a very good practice but we should learn which tests are useful and which ones are counterproductive. Coverage for 100 of lines is not the same coverage for 100 of code paths. Applying the Pareto principle what is the benefit of 100 versus say 80 coverage?Unit Testing.
