# generate-subunit

generate-subunit is a simple tool to, as its name implies, generate a subunit stream. It will generate a stream with a single test result to STDOUT. The subunit protocol lets you concatenate multiple streams together so if you want to generate a stream with multiple just append the output of multiple executions of generate-subunit.

## Summary

> generate-subunit timestamp secs [status] [test_id]

## Usage

generate-subunit has 2 mandatory arguments. These are needed to specify when the "test" started running and how long it took. The first argument is a POSIX timestamp (which can returned by the date util using `date +%s`) for when it started running. The second argument is the number of seconds it took for the execution to finish. For example:

    $ generate-subunit $(date +%s) 42

will generate a stream with the test_id 'devstack' successfully running for 42 secs starting when the command was executed. This leads into the 2 optional arguments. The first optional argument is for specifying the status. This must be the 3rd argument when calling generate-subunit. Valid status options can be found in the testtools documentation. If status is not specified it will default to success. For example:

    $ generate-subunit $(date +%s) 42 fail

will be the same as the previous example except that it marks the test as failing.

The other optional argument is the test_id (aka test name) and is used to identify the "test" being run. For better or worse this defaults to devstack. (which is an artifact of why this tool was originally created) Note, this must be the 4th argument when calling generate-subunit. This means you also must specify a status if you want to set your own test_id. For example:

    $ generate-subunit %(date +%s) 42 fail my_little_test

will generate a subunit stream as before except instead the test will be named my_little_test.
