Tryouts v2.0 ALPHA
Don't waste your time writing tests.
NOTE: Tryouts syntax changed since 0.x. The old version is still available in the 0.8-FINAL branch.
Check out the screencast created by Alex Peuchert.
## A very simple test 1 + 1 #=> 2 ## The test description can spread ## across multiple lines. The same ## is true for test definitions. a = 'foo' b = 'bar' a + b #=> 'foobar' ## A test will pass when its return ## value equals the expectation. 'foo'.class #=> String ## The expectations are evaluated. 1 + 1 #=> 1 + 1 ## Here's an example of testing errors begin raise RuntimeError rescue RuntimeError :success end #=> :success
For real world examples, see the Gibbler tryouts.
Setup / Cleanup
All code before the first test definition is assumed to be setup code. All code after the last definition is assumed to be cleanup code. Here is an example:
# This is called before all tests require 'gibbler' Gibbler.digest_type = Digest::SHA256 ## A Symbol can gibbler :anything.gibbler #=> '754f87ca720ec256633a286d9270d68478850b2abd7b0ae65021cb769ae70c08' # This will be called after all tests Gibbler.digest_type = Digest::SHA1
Try ships with a command-line tool called try. When called with no arguments, it will look for files ending with _try.rb in the current directory, or in the subfolder try.
You can also supply a specific file to test.
$ try path/2/test.rb Ruby 1.9.1 @ 2011-01-06 12:38:29 -0500 # TEST 1: test matches result with expectation 7 a = 1 + 1 8 #=> 2 == 2 ... ## TEST 12: comments, tests, and expectations can ## contain multiple lines 13 a = 1 14 b = 2 15 a + b 16 # => 3 17 # => 2 + 1 == 3 == 3 12 of 12 tests passed (and 5 skipped)
If all tests pass, try exits with a 0. Otherwise it exits with the number of tests that failed.
For reduced output, use the `-q` option:
$ try -q Ruby 1.9.1 @ 2011-01-06 12:38:29 -0500 42 of 42 tests passed (and 5 skipped) 4 of 4 batches passed
$ gem install tryouts
