/**
 * Aggregates all downstream-test-related tasks. It can be configured to run e2e tests on provided repositories.
 * E2E test for each downstream repository is divided into a few stages:
 *  - clone downstream project to '$buildDir/downstream'
 *  - execute 'testRelease' task using the newest Shipkit version inside the downstream clone
 *  - saves output logs to file or creates gists for them (see {@link UploadGistsTask})
 *
 * Adds tasks:
 * <ul>
 *     <li>clone$projectName - {@link CloneGitRepositoryTask}</li>
