Junit report is not updated after run tests on gitlab - docker

Question

I run automated tests on gitlab ci with gitlab runner, all works good except reports. After tests junit reports are not updated, always show the same pass and not pass tests even thought cmd show different number of passed tests.
Gitlab script:
stages:
- build
- test
docker-build-master:
image: docker:latest
stage: build
services:
- docker:dind
before_script:
- docker login -u "xxx" -p "yyy" docker.io
script:
- docker build ./AutomaticTests --pull -t "dockerImage"
- docker image tag dockerImage xxx/dockerImage:0.0.1
- docker push "xxx/dockerImage:0.0.1"
test:
image: docker:latest
services:
- docker:dind
stage: test
before_script:
- docker login -u "xxx" -p "yyy" docker.io
script:
- docker run "xxx/dockerImage:0.0.1"
artifacts:
when: always
paths:
- AutomaticTests/bin/Release/artifacts/test-result.xml
reports:
junit:
- AutomaticTests/bin/Release/artifacts/test-result.xml
Dockerfile:
FROM mcr.microsoft.com/dotnet/core/sdk:2.1
COPY /publish /AutomaticTests
WORKDIR /AutomaticTests
RUN apt-get update -y
RUN apt install unzip

I had a similar issue when using docker-in-docker for my gitlab pipeline. You run your tests inside your container. Therefore, test results are stored inside your "container-under-test". However, the gitlab-ci paths reference not the "container-under-test", but the outside container of your docker-in-docker environment.
You could try to copy the test results from the image directly to your outside container via something like this:
mkdir reports
docker cp $(docker create --rm DOCKER_IMAGE):/ABSOLUTE/FILEPATH/IN/DOCKER/CONTAINER reports/.
So, this would be something like this in your case (untested...!):
...
test:
image: docker:latest
services:
- docker:dind
stage: test
before_script:
- docker login -u "xxx" -p "yyy" docker.io
script:
- mkdir reports
- docker cp $(docker create --rm xxx/dockerImage:0.0.1):/AutomaticTests/bin/Release/artifacts/test-result.xml reports/.
artifacts:
when: always
reports:
junit:
- reports/test-result.xml
...
Also, see this post for furhter explanation on the docker cp command: https://stackoverflow.com/a/59055906/6603778
Keep in mind, that docker cp requires an absolute path to the file you want to copy from your container.
