quick-start

 Quick Start

Once your application is release, up and running. You only need the following three steps to do run-time coverage collection:

  • Step 1、Connects a shell to the running node which your application is running:
/path/bin/your_app remote_console
  • Step 2、Specific the application start coverage collection:
ExIntegrationCoveralls.start_app_cov("your_app_name")

Note: the your_app_name must exist in the return app list of :application.which_applications.

  • Step 3、Conduct external testing against the above application. Get run-time coverage or post coverage data to coverage system.
ExIntegrationCoveralls.get_app_total_cov("your_app_name")
# post coverage data
ExIntegrationCoveralls.post_app_cov_to_ci(url, extends, "your_app_name")

Note: Your application release package should include the source code. ExIntegrationCoveralls will use the source code to caculate coverage stats. The general structure is as follows:

.
├── bin
│   ├── explore_ast_app
│   ├── explore_ast_app.bat
│   ├── explore_ast_app_rc_exec.sh
│   ├── no_dot_erlang.boot

Note: If you use the distillery to get OTP release, and config set include_src: true, then you can get the above structure. But if you use the Elixir origin mix release, this situation needs to be handled manually.
