You can debug TestRun workflow using DEBUG environment variable. If debugging enabled tescafe will log following events to console:

• tescafe:test-run:{userAgent}:driver-message - incoming message from Driver.
• tescafe:test-run:{userAgent}:command - TestRun started execution of the command.

You can enable debugging by specifying environment variable.

Example using gulp:

DEBUG=testcafe:test-run:* gulp test-functional

This will log all kinds of messages for all user-agents. As you see you can use wildcards (*) to filter messages.

Filtering examples:

DEBUG=testcafe:test-run:Chrome*:* gulp test-functional

Will log only message for Chrome only.

DEBUG=testcafe:test-run:*:error gulp test-functional

Will log only error messages.

Just like in local usage you need to specify environment variable. You can do it for the specific task in .travis.yml file.

Example:

language: node_js
matrix:
 include:
  - node_js: "0.10"
    env: GULP_TASK="test-server"
  - node_js: "4"
    env: GULP_TASK="test-server"
  - node_js: "stable"
    env: GULP_TASK="test-server"
  - node_js: "stable"
    env: GULP_TASK="test-client-travis"
  - node_js: "stable"
    env: GULP_TASK="test-functional" DEBUG="testcafe:test-run:*"
 fast_finish: true
