# GstValidate Test file
|
|
|
|
A `.validatetest` file describes a fully contained validate test case. It
|
|
includes the arguments of the tool supposed to be used to run the test as well
|
|
as possibly a [configuration](gst-validate-config.md) and a set of action to
|
|
describe the validate [scenario](gst-validate-scenarios.md).
|
|
|
|
# The file format
|
|
|
|
A validate test file requires a `meta` structure which contains the same
|
|
information as the [scenario](gst-validate-scenarios.md) `meta` with some
|
|
additional fields described below. The `meta` structure should be either the
|
|
first or the one following the `set-globals` structure. The `set-globals`
|
|
structures allows you to set global variables for the rest of the
|
|
`.validatetest` file and is a free form variables setter. For example you can
|
|
do:
|
|
|
|
``` yaml
|
|
set-globals, media_dir=$(test_dir)/../../media
|
|
```
|
|
|
|
## Tool arguments
|
|
|
|
In the case of [`gst-validate`](gst-validate.md) it **has to** contain an
|
|
`args` field with `gst-validate` argv arguments like:
|
|
|
|
``` yaml
|
|
# This is the default tool so it is not mandatory for the `gst-validate` tool
|
|
tool = "gst-validate-$(gst_api_version)",
|
|
args = {
|
|
# pipeline description
|
|
videotestrc num-buffers=2 ! $(videosink),
|
|
# Random extra argument
|
|
--set-media-info $(test-dir)/some.media_info
|
|
}
|
|
```
|
|
|
|
## configs
|
|
|
|
The `configs` field is an array of structures containing the same content as
|
|
usual [configs](gst-validate-config.md) files.
|
|
|
|
For example:
|
|
|
|
``` yaml
|
|
configs = {
|
|
# Set videotestsrc0 pattern value to `blue`
|
|
"core, action=set-property, target-element-name=videotestsrc0, property-name=pattern, property-value=blue",
|
|
"$(validateflow), pad=sink1:sink, caps-properties={ width, height };",
|
|
}
|
|
```
|
|
|
|
Note: Since this is GstStructure synthax, we need to have the structures in the
|
|
array as strings/within quotes.
|
|
|
|
## expected-issues
|
|
|
|
The `expected-issues` field is an array of `expected-issue` structures containing
|
|
information about issues to expect (which can be known bugs or not).
|
|
|
|
Use `gst-validate-1.0 --print-issue-types` to print information about all issue types.
|
|
|
|
For example:
|
|
|
|
``` yaml
|
|
expected-issues = {
|
|
"expected-issue, issue-id=scenario::not-ended",
|
|
}
|
|
```
|
|
|
|
Note: Since this is GstStructure synthax, we need to have the structures in the
|
|
array as strings/within quotes.
|
|
|
|
### Fields:
|
|
|
|
* `issue-id`: (string): Issue ID - Mandatory if `summary` is not provided.
|
|
* `summary`: (string): Summary - Mandatory if `issue-id` is not provided.
|
|
* `details`: Regex string to match the issue details `detected-on`: (string):
|
|
The name of the element the issue happened on `level`: (string):
|
|
Issue level
|
|
* `sometimes`: (boolean): Default: `false` - Wheteher the issue happens only
|
|
sometimes if `false` and the issue doesn't happen, an error will
|
|
be issued.
|
|
* `issue-url`: (string): The url of the issue in the bug tracker if the issue is
|
|
a bug.
|
|
|
|
### Variables
|
|
|
|
The same way
|
|
|
|
Validate testfile will define some variables to make those files relocable:
|
|
|
|
* `$(test_dir)`: The directory where the `.validatetest` file is in.
|
|
|
|
* `$(test_name)`: The name of the test file (without extension).
|
|
|
|
* `$(test_name_dir)`: The name of the test directory (test_name with folder
|
|
separator instead of `.`).
|
|
|
|
* `$(validateflow)`: The validateflow structure name with the default/right
|
|
values for the `expectations-dir` and `actual-results-dir`
|
|
fields. See [validateflow](gst-validate-flow.md) for more
|
|
information.
|
|
|
|
* `$(videosink)`: The GStreamer videosink to use if the test can work with
|
|
different sinks for the video. It allows the tool to use
|
|
fakesinks when the user doesn't want to have visual feedback
|
|
for example.
|
|
|
|
* `$(audiosink)`: The GStreamer audiosink to use if the test can work with
|
|
different sinks for the audio. It allows the tool to use
|
|
fakesinks when the user doesn't want to have audio feedback
|
|
for example.
