XSpec is a unit test and behaviour-driven development (BDD) framework for XSLT, XQuery, and Schematron.

This is the Docker image for XSpec v0.5.0.

Building instructions are relevant until the XSpec Docker image is accepted in Docker Hub.

Clone the repository, go to the directory where the Dockerfile is located, and build the Docker image as follow:

docker build -t xspec:latest .

Run the Docker container with no arguments to check that it works correctly:

docker run xspec

This should output the help:

Saxon script not found, invoking JVM directly instead.

Usage: xspec [-t|-q|-c|-j|-h] filename [coverage]

  filename   the XSpec document
  -t         test an XSLT stylesheet (the default)
  -q         test an XQuery module (mutually exclusive with -t)
  -c         output test coverage report
  -j         output JUnit report
  -h         display this help message
  coverage   deprecated, use -c instead

Now run it with the default tutorial file included in XSpec:

docker run xspec /xspec/tutorial/escape-for-regex.xspec

This should output the following:

Saxon script not found, invoking JVM directly instead.

Formatting Report...
passed: 5 / pending: 0 / failed: 1 / total: 6
Report available at /xspec/tutorial/xspec/escape-for-regex-result.html
Done.

In the example above both the XSpec test escape-for-regex.xspec and the report /xspec/tutorial/xspec/escape-for-regex-result.html are stored within the container and are not accessible from the host as the container exits at the end of its execution.

To make the report accessible from the localhost and to pass an XSpec test file stored on the localhost, run it with the -v flag. This allows to map a volume on the localhost with a volume inside the container. For example:

docker run -v /tmp:/input xspec /input/mytest.xspec

where

• /tmp is the directory on your localhost where mytest.xspec and the relevant XSLT you want to test are stored (in other words /tmp/mytest.xspec must exist on your machine)
• /input is just a convention to define a volume inside the container (in other words input can be replaced with anything you like)

This runs the XSpec test mytest.xspec inside the Docker container and ends with the message:

...
Report available at /input/xspec/mytest-result.html
Done.

As /input is mapped to /tmp on your localhost, the report is available at /tmp/xspec/mytest-result.html.

IMPORTANT: Make sure that /tmp (or any other directory you want to map with the -v flag) has 777 permissions as XSpec runs as an unprivileged user inside Docker and needs to write and remove temporary files. To change permissions on your local /tmp directory use:

sudo chmod 777 /tmp

Finally, you can pass any additional parameter that it is supported by XSpec. For example, to run an XSpec test for XQuery add -q:

docker run -v /tmp:/input xspec -q /input/mytest.xspec

At the moment the report is not able to access the CSS file because the path to /xspec/src/reporter/test-report.css is only available inside the container. Creating a directory /xspec/src/reporter on the local host and copying manually the CSS file from the XSpec project is a workaround to display the report with the CSS formatting until this issue is fixed.
