tea-time v2.1.2

Unit test: Tea Time!

This is a battery included mocha-compatible test framework.

For the doc, start reading the mocha documentation.

Specific Tea Time! features:

• Many reporters can be used at once, just using multiple --reporter options in the CLI

• NEW! Promise-returning (or async function) tests and hooks

• NEW! Built-in expect assertion (but custom assertion lib can be used as well), through the expect global function

• NEW! (beta) Built-in test coverage, with in-terminal report, example:

  tea-time -C

  ... or even better using a pager:

  tea-time -C | less -r

• Run browser tests directly from the CLI! So you can script browser tests as well! This example will grab all test in the test directory and build a browser version of them using Browserify, create a HTML target file in the OS tmp directory, open it using Firefox, run the test in Firefox while reporting anything to Tea Time (using websocket behind the scene).

  tea-time test/*js --tmp-html --ws --browserify --browser firefox

  ... or use the shorthand:

  tea-time test/*js --bb firefox

• Optional tests:

  	When an optional test fails, it does not cause a 'fail' but an 'optionalFail'.
  	Optional fails don't produce non-zero exit code.
  	Common use cases are next iteration preparation, or test cases created just after a bug discovery: we do not want those
  	fails to prevent new releases since there is no regression.
  
  	Syntaxes:
  	- .optional()
  	- .opt()
  	- .next()

  it.optional( "Optional test" , function( done ) {
      throw new Error( "Optional fail" ) ;
  } ) ;

• Better test isolation, mocha (v3.0.2 ATM) would fail to run this test properly:

  describe( "Desync" , function() {
      
      it( "should timeout and fail after the timeout" , function( done ) {
          
          this.timeout( 100 ) ;
          
          setTimeout( function() {
              throw new Error( "Delayed fail" ) ;
          } , 200 ) ;
      } ) ;
      
      it( "should pass without being affected by the previous test after-timeout failure" , function( done ) {
          
          setTimeout( function() {
              done() ;
          } , 500 ) ;
      } ) ;
  } ) ;

Install

Install it globally: npm install -g tea-time.

Usage

Usage is: tea-time test files option2

Available options:

  -h , --help             Show this help
  -C , --cover            Perform test coverage (beta feature, node.js only)
  -t , --timeout <time>   Set the default timeout for each test (default: 2000ms)
  -s , --slow <time>      Set the default slow time for each test (default: 75ms)
  -g , --grep <pattern>   Grep: filter in tests/suites by this pattern (can be used multiple times)
  -c , --console          Allow console.log() and friends
  -b , --bail             Bail after the first test failure
  -O , --skip-optional    Skip optional tests
  -R , --reporter <name>  Set/add the reporter (can be used multiple times)
 --clientReporter <name>  Set/add the client reporter (see --browser, can be used multiple times)
       --html <file>      Build one HTML file for all input test files, to run the test in browsers
       --tmp-html         Like --html but create a temporary file in the OS temp folder
       --browserify       In conjunction with --html, call Browserify to build a browser version
                          for each input files
       --ws               Start a websocket server, endpoint to the browser websocket client reporter
  -B , --browser <exe>    Open the html with the <exe> browser, need --html <file>,
                          force --ws and the websocket client reporter
       --bb <exe>         Shorthand for --tmp-html --ws --browserify --browser <exe>

• one-line: one line status
• panel: a reporter that does not scroll (except on the final error report, if any)
• progress: a progress bar reporter
• tap: Test Anything Protocol
• dot: output colorful dots
• verbose: like classic, but more verbose
• report: use in conjunction with another reporter, only output the final status report
• error-report: use in conjunction with another reporter, only output the final error report
• coverage-summary: use in conjunction with another reporter, output partly uncovered files with percent
• coverage-report: use in conjunction with another reporter, output all uncovered lines of code
• notify: use in conjunction with another reporter, send a freedesktop.org notification with the final status report

Browser reporters:

• classic: the default reporter
• console: report everything in the browser console, using console.log()
• websocket: connect to a local Tea Time instance, and send anything to it
