How do I find the Test Coverage of my code during the build process automatically, and ensure that if coverage is below 80%, build should fail.
So, is it possible that as part of my gradle build process when the test case runs, there should also be another testcase, which should find the test-coverage percentage and apply assertions to ensure coverage %age > 80?
Can we get this through JUnits only. I don;t want to externally check the coverage in eclipse.
Yes you can, please have a look at this project:

My project is build by Bazel. Except for the unit test for every single function, it sometimes needs testing in some scenes like the simulation of the user's input as a black box testing. To ensure the testing scene is complex enough to find vulnerabilities, I want to know the coverage of some testing scenes.
I try to avoid writing unit tests, like using LLVM flags -fprofile-instr-generate -fcoverage-mapping and running the test program directly, interacting with the program, and then getting coverage.
I read from Bazel's documents know the coverage command runs the unit test to get coverage, but can I directly get coverage from a running program?
I am using gtest in VS2019. I have one hundred tests in ten test suites. When I run all tests, and some tests fail, then some test suites are skipped in entirety.
I did not mark any test as skipped.
I feel that this happens when some of the fails are memory issues(invalid pointer etc). When I fix the errors and rerun, everything runs.
Why does this happen? How do I make sure every test runs when I hit "run all"?
you need to change the way you run the test,
for that, what I suggest is create a test project file then, paste your files there and then click the build and run button the tests would open up as terminal and all tests would run, just as gtest works on linux; terminal based
I am trying to get TeamCity set up for a project. I want to run a scheduled build that includes a step where NUnit Tests are run.
My NUnit build step looks like this:
Runtime: NUnit-2.6.3 v4.0 MSIL
Run tests on: **/Tests/*.dll
Execute: If all previous steps finished successfully
But every time I run the build I get an error saying:
No assemblies were found.
Why is this happening and how can I fix it? Also, conceptually, this build step will happen BEFORE the project is actually built. But how will there be any Test DLLs (assemblies) unless the project is built in the first place?
I would suggest that you build your projects before running tests. Most common way to achieve this is that you have separate configurations for building code and running tests.
Your build configuration would generate artefacts (containing assemblies most likely).
Test run configuration would extract this artefact package, via artefacts dependency, then in build step you run tests from specific assembly.
This is the most common approach and using this approach you do not have to worry about files in the files system. Teamcity's snapshot isolation and artefacts dependencies will take care of this (when properly configured)
If you need an example how to achieve this, let me know.
I'm using Xcode 3.2.2 and the built in OCUnit test stuff. One problem I'm running into is that every time I do a build my unit tests are run, even if the build failed. Let's say I make a syntax error in one of my tests. The test fails to compile and the last successful compilation of the unit tests are run. The same thing happens if one of the dependent targets fail to build - the tests are still run. Which is obviously not what I want.
How can I prevent the tests from running if the build fails? If this is not possible then I'd rather have the tests never run automatically, is that possible? Sorry if this is obvious, I'm an Xcode noob. Should I be using a better unit testing framework?
The answer is to dump OCUnit and use GHUnit which is about a million times better:

All you need to do is make the script that runs the unit tests dependent on your test bundle having been built. To do this:
In your Targets group expand your unit test bundle and Get Info on the Run Script.
On the general tab click the + button for the Input Files and enter:
$(BUILT_PRODUCTS_DIR)/$(EXECUTABLE_PATH)
What are the steps to get Team Foundation Server running unit tests when a given build runs?
What are the caveats / pitfalls / workarounds a dev or sysadmin should be aware of when setting up a TFS server to do this for the first time?
What are common troubleshooting steps for unit test problems during builds?
it depends on which version of TFS you are running, so I will assume it is 2008.
Firstly, you must have Team Edition for Testers installed on the computer that will act as your build agent, as stated in How To: Create a Build Definition
There are a couple of ways to tell Team Build to run tests for your build.
Unit tests can be run from a defined Test List within the Solution being built. This list is referenced by the build definition and all tests within the chosen list(s) are executed. More info here
WildCard test exectution is also available by defining a wildcard mask (i.e. Test*.dll) that instructs Team Build to run any tests present in assemblies that match the mask. This is done when defining the build definition as well.
Things to note:
If you intend to use the wildcard method and want to enable code coverage for your test configuration, you must add the following to your build definition file to enable it.
<RunConfigFile>$(SolutionRoot)\TestRunConfig.testrunconfig</RunConfigFile>
See my previous question on this for more info here
If you don't want to use test configs (A Pain in the ass to manage) just run all the test in a .dll by adding this to the build config:
<ItemGroup>
<TestContainerInOutput Include="MyProject.UnitTests.dll" />
</ItemGroup>
The whole process is smooth and fairly simple. You can inspect the unit tests that filaed on the build server by opening the test result file locally (a bit of a pain) but generally you'll just run the unit tests locally and you can see the results immediately.
If you are used to NUnit, you may opt to sort the tests by classname, it gives a similar view.
Careful with code coverage, it makes complete copies of your binaries on compile. If your binaries are sufficiently large and you compile often, it will eat through drive space quickly.
