Problem with QGIS docker and documentation

[manylon]

What is the bug or the crash?

I am using the qgis_testrunner.sh script to run unit tests for a QGIS-Plugin.

The qgis_testrunner.sh was either missing or returning this ERROR: no output from the test runner! (exit code: 0)
I followed the documentation from QGIS Docker images

This is a similar issue to #54314

Steps to reproduce the issue

Reproducing the problem:
Cleaning cache from docker, just in case:

$ docker builder prune 

$ cd QGIS
$ docker build -t qgis/qgis:release-3_36 --build-arg DOCKER_TAG=release-3_36 -f .docker/qgis.dockerfile .

Response starts with:

[internal] load .dockerignore
 => => transferring context: 71B
 => [internal] load build definition from qgis.dockerfile
 => => transferring dockerfile: 2.33kB
 => [internal] load metadata for docker.io/qgis/qgis3-build-deps:latest  

Reminder I am using version = release-3_36

I guess it comes from .docker/qgis.dockerfile

ARG DOCKER_DEPS_TAG=latest

Running the container:

$ xhost + 127.0.0.1
$ docker run --rm -it --name qgis36 -v /dir:/tests_directory/plugin_name -e DISPLAY=host.docker.internal:0 qgis/qgis:release-3_36

Check if the build is successful:

$ docker exec -it qgis36 sh -c "cd /QGIS && cat build_exit_value"

Response:

FAILED

Test test_runner.sh:

$ docker exec -it qgis36 sh -c "cd /tests_directory && qgis_testrunner.sh"

Response:

qgis_testrunner.sh: not found

In some cases the response was:

ERROR: no output from the test runner! (exit code: 0)

Did the same with the latest version:

$ docker builder prune 
$ docker build -t qgis/qgis:latest --build-arg DOCKER_TAG=release-3_36 -f .docker/qgis.dockerfile .
$ xhost + 127.0.0.1
$ docker run --rm -it --name qgislatest -v /dir:/tests_directory/plugin_name -e DISPLAY=host.docker.internal:0 qgis/qgis:latest

Check if the build is successful:

$ docker exec -it qgislatest sh -c "cd /QGIS && cat build_exit_value"

Response:

FAILED

$ docker exec -it qgislatest sh -c "cd /tests_directory && qgis_testrunner.sh"

Response:

qgis_testrunner.sh: not found

The successful solution was without using .docker/qgis.dockerfile:

$ docker builder prune 
$ docker pull qgis/qgis:release-3_36 
$ xhost + 127.0.0.1
$ docker run --rm -it --name qgis36 -v /dir:/tests_directory/plugin_name -e DISPLAY=host.docker.internal:0 qgis/qgis:release-3_36

Check if the build is succesful:

$ docker exec -it qgis36 sh -c "cd /QGIS && cat build_exit_value"

Response:

OK

Test qgis_testrunner:

$ docker exec -it qgis36 sh -c "qgis_testrunner.sh"

Response:

ValueError: Empty module name
Finished running test (codes: IS_DEAD=1 IS_FAILED=0 IS_PASSED=1).

Setup developing plugin:

$ docker exec -it qgis36 sh -c "qgis_setup.sh plugin_name"

Test plugin

$ docker exec -it qgis36 sh -c "cd /tests_directory && qgis_testrunner.sh plugin_name.tests.test_something"

Response:

Works

Versions

Is this an issue with https://github.com/qgis/qgis-docker ? If it is, can you move it there?

[manylon]

My guess is that it is coming from .docker/qgis.dockerfile because I succeded building without using it.

I've just opened qgis/qgis-docker#114 as I ran into a similar issue: missing qgis_setup.sh.
To me, it looks like the Dockerfile in this repository is not being used anymore, but instead https://github.com/qgis/qgis-docker/blob/main/desktop/Dockerfile

And.... that one installs qgis from a debian package, which doesn't include the custom shell scripts copied by "our" dockerfile from somewhere in the .docker/ directory:

# Add QGIS test runner
COPY .docker/qgis_resources/test_runner/qgis_* /usr/bin/
