FileExistsWaitStrategy class

Waits until a specific file exists on the container's filesystem.

Runs test -f <filePath> inside the container on each poll attempt via exec. A zero exit code means the file exists. On timeout, a diagnostic ls of the parent directory is run inside the container to help identify why the file was not created.

Example:

container.waitingFor(FileExistsWaitStrategy('/tmp/ready'));
