Building
Before building the project, the following tools must be installed:
This project is built with Gradle. After installing the pre-requisites, run:
./gradlew
Building Behind a Proxy
Since this project downloads its dependencies from the internet, building behing a proxy requires some extra effort. In order configure gradle properly, use the following system properties. More information can be found here.
./gradlew -Dhttp.proxyHost=<HOST> -Dhttp.proxyPort=<PORT>
Deploying to Cloud Foundry
Each test application contains a manifest.yml file which allows the built application to be deployed to Cloud Foundry by simply issuing:
cf push
To avoid clashing with the URLs of other applications, you should specify your own subdomain for the application (unless the test application does not need a subdomain).
Failure Testing
Failure testing is supported for each of the above applications by setting a suitable environment variable.
If the environment variable FAIL_INIT is set, the application will fail to initialize:
cf set-env <application name> FAIL_INIT true
If the environment variable FAIL_OOM is set, the application will repeatedly exhaust the heap until the JVM is killed:
cf set-env <application name> FAIL_OOM true
Running Tests
To run the tests, do the following:
./gradlew
