 # Running the tests
 
 * By default, tests run against our Staging instance, but you can pass in a different location if you want to run the tests against e.g. your local build
 
 ## Using tap
-* Run all tests in the smoke-testing directory from the command-line: `$ make smoke`
-* To run a single file from the command-line: `$ node_modules/.bin/tap ./test/integration/smoke-testing/filename.js --timeout=3600`

   * The timeout var is for the length of the entire tap test-suite; if you are getting a timeout error, you may need to adjust this value (some of the Selenium tests take a while to run)
