Testing

Prerequisites

You need to ensure you have the following tools installed:

• Docker 19.03 or higher (API version 1.40)
• GNU make
• Go - only needed for running the tests

Running the tests

There are two main sets of tests:

1. Unit tests, which are run during a build
2. Docker tests, which test a complete Docker image, using the Docker API

Running the Docker tests

The Docker tests can be run locally on a machine with Docker. For example:

make test-devserver
make test-advancedserver

You can specify the image to use directly by using the MQ_IMAGE_ADVANCEDSERVER or MQ_IMAGE_DEVSERVER variables, for example:

MQ_IMAGE_ADVANCEDSERVER=ibm-mqadvanced-server:9.3.2.0-amd64 make test-advancedserver

You can pass parameters to go test with an environment variable. For example, to run the "TestGoldenPath" test, run the following command:

TEST_OPTS_DOCKER="-run TestGoldenPath" make test-advancedserver

You can also use the same environment variables you specified when building, for example, the following will try and test an image called ibm-mqadvanced-server:9.2.0.0-amd64:

MQ_VERSION=9.2.0.0 make test-advancedserver

Running the Docker tests with code coverage

You can produce code coverage results from the Docker tests by running the following:

make build-advancedserver-cover
make test-advancedserver-cover

In order to generate code coverage metrics from the Docker tests, the build step creates a new Docker image with an instrumented version of the code. Each test is then run individually, producing a coverage report each under test/docker/coverage/. These individual reports are then combined. The combined report is written to the coverage directory.
