Setup contexts

The setup context functions return a context object that the test disposes with await using. The context has an element and an owner from your app.

• setupContext, for an owner to look up services, without rendering
• setupRenderingContext, for rendering with @ember/test-helpers

WARNING

Tests that use setupRenderingContext cannot run in parallel. It calls setApplication and setupContext from @ember/test-helpers, and both store their state in global variables. Parallel tests overwrite the state of each other.

setupContext does not use these global variables.
