Running Tests

To run tests with coverage data, run the following command:

mix test --cover --exclude real_cover
# run all test cases
mix test

Installation

The package can be installed by adding ex_integration_coveralls to your list of dependencies in mix.exs:

def deps do
  [
    {:ex_integration_coveralls, "~> 0.7.0"}
  ]
end

The docs can be found at https://hexdocs.pm/ex_integration_coveralls.

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. The general structure is as follows:
