To view results from a previous session, choose Import Code Coverage Results, navigate to the TestResults folder in your solution, and import a. The menu shows a temporary list that is cleared when you open a new solution. To view a previous set of results, select it from the drop-down menu. You can merge the results of several runs, for example from runs that use different test data. The Code Coverage Results window can also be used to view previous results, or results obtained on other computers. The results will vary if you change your test data, or if you run only some of your tests each time. The Code Coverage Results window usually shows the result of the most recent run. If some but not all code blocks in the line are exercised, it is counted as a partial line. If this is the case, and the test run exercises all the code blocks in the line, it is counted as one line. A line of code can contain more than one code block. In your tsconfig.json file change rootDir parameter to. With this change you also need to change a couple of parameters in your tsconfig.json file and package.json file. To fix this, move test folder out of src folder so they will be on the same level. The problem with tests code coverage arise from a simple fact that coverage is measured for src folder and tests code is there as well. That doesn’t seem right, so let’s fix it by some structural changes. It looks really nice, but you may noticed one small problem here that tests code was covered as well. You now can open index.html file there to see HTML-based report. Yay! All the information related to code coverage was saved to coverage folder in the root of your extension.
