|
|
|
|
The suites directory has a hierarchical collection of tests. This can be
|
|
freeform, but generally follows the convention of
|
|
|
|
suites/<test suite name>/<test group>/...
|
|
|
|
A test is described by a yaml fragment.
|
|
|
|
A test can exist as a single .yaml file in the directory tree. For example:
|
|
|
|
suites/foo/one.yaml
|
|
suites/foo/two.yaml
|
|
|
|
is a simple group of two tests.
|
|
|
|
A directory with a magic '+' file represents a test that combines all
|
|
other items in the directory into a single yaml fragment. For example:
|
|
|
|
suites/foo/bar/+
|
|
suites/foo/bar/a.yaml
|
|
suites/foo/bar/b.yaml
|
|
suites/foo/bar/c.yaml
|
|
|
|
is a single test consisting of a + b + c.
|
|
|
|
A directory with a magic '%' file represents a test matrix formed from
|
|
all other items in the directory. For example,
|
|
|
|
suites/baz/%
|
|
suites/baz/a.yaml
|
|
suites/baz/b/b1.yaml
|
|
suites/baz/b/b2.yaml
|
|
suites/baz/c.yaml
|
|
suites/baz/d/d1.yaml
|
|
suites/baz/d/d2.yaml
|
|
|
|
is a 4-dimensional test matrix. Two dimensions (a, c) are trivial (1
|
|
item), so this is really 2x2 = 4 tests, which are
|
|
|
|
a + b1 + c + d1
|
|
a + b1 + c + d2
|
|
a + b2 + c + d1
|
|
a + b2 + c + d2
|
|
|
|
A directory with a magic '$' file, or a directory whose name ends with '$',
|
|
represents a test where one of the non-magic items is chosen randomly. For
|
|
example, both
|
|
|
|
suites/foo/$
|
|
suites/foo/a.yaml
|
|
suites/foo/b.yaml
|
|
suites/foo/c.yaml
|
|
|
|
and
|
|
|
|
suites/foo$/a.yaml
|
|
suites/foo$/b.yaml
|
|
suites/foo$/c.yaml
|
|
|
|
is a single test, either a, b or c. This can be used in conjunction with the
|
|
'%' file in the same (see below) or other directories to run a series of tests
|
|
without causing an unwanted increase in the total number of jobs run.
|
|
|
|
Symlinks are okay.
|
|
|
|
One particular use of symlinks is to combine '%' and the latter form of '$'
|
|
feature. Consider supported_distros directory containing fragments that define
|
|
os_type and os_version:
|
|
|
|
supported_distros/%
|
|
supported_distros/centos.yaml
|
|
supported_distros/rhel.yaml
|
|
supported_distros/ubuntu.yaml
|
|
|
|
A test that links supported_distros as distros (a name that doesn't end with
|
|
'$') will be run three times: on centos, rhel and ubuntu. A test that links
|
|
supported_distros as distros$ will be run just once: either on centos, rhel or
|
|
ubuntu, chosen randomly.
