Enable code coverage indication in Android Studio Gutter - unit-testing

When I run my unit tests in the android studio with code coverage and select to see the source from the Coverage toolbar, I cannot see the code coverage information in the gutter(sidebar) of the editor as shown here. There is no information about the number of hits or color indicators in the gutter.
This is what I am using:
Android Studio 3.2.1
Build #AI-181.5540.7.32.5056338, built on October 9, 2018
JRE: 1.8.0_152-release-1136-b06 amd64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Linux 4.15.0-34-generic

Go to configuration -> Unit test , click the drop down then click the project module you would like to enable coverage on then click code coverage and enable tracing . Also click on Analyze then Show code coverage data .

Run tests with Code coverage
Go to that class you write a test for
You can see the coverage indication on gutter

How to disable test discovery in visual studio 2017?

I have some solutions with a bunch of projects and we have no unit test project in these solutions. However Visual Studio 2017 is still trying to discover unit tests and slowing down our process.

I looked at the runsettings xml file but there was nothing in there to disable it
https://learn.microsoft.com/en-us/visualstudio/test/configure-unit-tests-by-using-a-dot-runsettings-file
any idea how we turn this unnecessary stuff off for some of our solutions?
Thanks
This was driving me crazy too. One day it just started running test discovery after every build, and switching my output pane to "Test" which is annoying.
How I fixed it in VS 2015 (may be the same for 2017),
disable (uncheck) this setting:
Test menu --> Test Settings --> Keep Test Execution Engine Running

visual studio code unit test discovery frequency setting

When I'm updating my existing unit tests, Visual Studio code drops a status bar from the top letting me know that it could not correctly discover unit tests every time I save the file. This is expected since I'm actively typing so everything is not working python.
Have I configured something incorrectly? Is there some way to tell visual studio to chill out on the unit test discovery?
Of course, I can simply hit the "close" button, but this is extremely distracting.
Disable Live Unit Test running on the background.
Under Test->Test Settings-> uncheck 'Keep Test Execution Engine Running'. I am using VS 2017 & VS 2015.

.net core test not showing correctly in VS 2015 Test Explorer

I am trying to build unit tests for my dotnet core project using xunit following these steps outlined here https://xunit.github.io/docs/getting-started-dotnet-core.html
The problem I have is that any updates to the the unit tests are not reflected in VS 2015 Test Explorer. I have tried building the solution and then running the tests, but it's still not showing up or it's using the old build.
If I run the tests from the command line using "dotnet test", then everything works fine. When I go to the Test Explorer here after, it shows the updated and new unit tests. But I can't get the same to work in VS Test Explorer.
What I do now is, go to the command line, run "dotnet test", go back to VS and "Run All" from the Test Explorer to get the view updated with the new test results.
It seems that doing the build in VS and selecting "Run All" doesn't affect the assemblies used by the Test Explorer.
Can you help me get everything working from VS itself?
I am using Visual Studio 2015 Update 3.
Just ran into the same problem today: disable the test settings if you have any loaded. After that they started successfully showing up for me.

How can I disable code coverage / assembly instrumentation in Visual Studio 2012?

I have a project upgraded from Visual Studio 2010 to 2012 and the .testrunconfig file was included in the upgrade process.
I noticed that it was possible to click "Analyze code coverage" on any of the unit tests that I had run and it would correctly display the result. However, my test run configuration (originally from VS 2010) had code coverage disabled.
After doing a bit of research I learned that the VS 2010 configuration files have been deprecated and replaced by .runsettings files. It would appear that VS 2012 enforces assembly instrumentation by default which has a massive overhead associated with it.
Therefore, I would like to know how I can disable code coverage in VS 2012. Based upon my current findings it does not seem to be a trival task. One recent article I read had me creating an XML file manually and naming it "MYCONFIGURATION.runsettings" and manually manipulating XML attribute values.
Does anyone know how this should be done?
This is what I understand from your post:
You have a Test project with .testsettings file. You have not enabled code coverage in the test settings.
Code coverage instrumentation is not enabled by default in your scenario. Binaries will be instrumented if you do 'analyze code coverage' from VS.
Additional Info:
You can confirm that .coverage file is not generated by running the following command from visual studio developer command prompt:
vstest.console.exe /Settings:<your test settings file> test.dll
A coverage file will only get generated if you have enabled coverage in test settings.
Code coverage is only enabled through the Test Explorer using data driven adapters. The metadata for tests ran through the test explorer is almost completely different than that of tests ran straight from the unit test session window. Have you tried simply running it straight from the code (the MSTest gui bubbles) or from the unit test session window?

TFS 2010 Build Automation - Enabling Code Coverage

How do you enable code coverage for unit testing in TFS2010 automatic build?
In Visual Studio 2010 we enabled Code Coverage for our test projects (Test --> Edit Test Settings --> Local Test Settings --> enable Code Coverage and choose assemblies to run code coverage against).
Now this is working fine (we can read code coverage) when running from Visual Studio 2010 (Test --> Run --> All Test In Solution).
The problem is that no code coverage is reported in TFS 2010 when building.
Note that the test projects are used by the build controller but without any code coverage.
Is very important for us to enable code coverage together with unit testing.
I forgot to mention that the problem I'm encountering has to do with code coverage for a web application project.
At step:
Test --> Edit Test Settings --> Local Test Settings --> enable Code Coverage and choose assemblies to run code coverage against
when choosing assemblies you can choose the web application. I think that the problem is related to Path (the value under the Path column from wizard) which is the one from developer machine (http://localhost...). When building and deploying with TFS the build goes on one server and the deployment on another.
The question should be now: which path should be available in testsettings. The build path or the deployment path?
Currently I'm not at work and can't test my doubts.
I'll let you know as soon as I get in touch with TFS.
You need to tell the build server which test settings file to use. You will find this in the build settings under Process >2. Basic >Automated Tests >1. Test Assembly >TestSettings file.
Once you have that specified then the Code coverage should work.
