Testing on the Raku track

Run All Tests

There is a Raku script with the extension .rakutest, which will be used to test your solution. You can run through the tests by using the command:

prove6

Before you start the exercise, the output will likely look something like:

# Failed test 'Say Hi!'
# at t/hello-world.rakutest line 6
# expected: "Hello, World!"
#  matcher: 'infix:<eq>'
#      got: "Goodbye, Mars!"
# You failed 1 test of 1
t/hello-world.rakutest ... Dubious, test returned 1
Failed 1/1 subtests

You will need to modify the module with the extension .rakumod, contained in the lib/ directory, and write a solution to pass the tests. Once the tests are passing, the output from the command above will likely look something like:

t/hello-world.rakutest ... ok
All tests successful.

Stop After First Failure

If you have the RAKU_TEST_DIE_ON_FAIL environment variable set, the test runner will stop after the first failure. For example:

In Linux / OS X:

export RAKU_TEST_DIE_ON_FAIL=1
# now all the follow up runs will stop at the first failure
prove6
# until we do
unset RAKU_TEST_DIE_ON_FAIL
# or you can use it for one run like this:
RAKU_TEST_DIE_ON_FAIL=1 prove6

Or in Windows:

SET RAKU_TEST_DIE_ON_FAIL=1
REM now all the follow up runs will stop at the first failure
prove6
REM until we do
set RAKU_TEST_DIE_ON_FAIL=

For more information see the Testing chapter of the Raku Documentation.

Troubleshooting

===SORRY!===
Could not find JSON::Fast

All modules used in the Raku track are included with Rakudo Star. If you get an error message such as the above when attempting to run a test, then you will either need to make sure you have the latest distribution of Rakudo Star, or install the module yourself using a package manager. See the Raku documentation on modules for information on how to install modules.
