The main concept is that all tests should use the image as is without any 'internal' go-related features. We, like users, receive the image and we are going to check what we've got.

The project has been started in Java as POC, however, I'm thinking about porting to python which is more suitable lang for the Ansible-oriented stack. Kindly ask you to raise the issue in case of any suggestions/bugs.

General image test

1. Download the latest shaded dist from https://github.com/dgroup/docker-unittests/releases:

   wget https://github.com/dgroup/docker-unittests/releases/download/s1.1.1/docker-unittests-app-1.1.1.jar
   

2. Define an *.yml file with tests.

   
   version: 1.1
   
   setup:
   - apt-get update
   - apt-get install -y tree
   
   tests:
   
   - assume: java version is 1.9, Debian build
     cmd:    java -version
     output:
       contains:
        - openjdk version "9.0.1"
        - build 9.0.1+11-Debian
   
   - assume: curl version is 7.xxx
     cmd:    curl --version
     output:
       startsWith: curl 7.
       matches:
        - "^curl\\s7.*\\n.*\\nProtocols.+ftps.+https.+telnet.*\\n.*\\n$"
       contains:
        - AsynchDNS IDN IPv6 Largefile GSS-API
   
   - assume:  Setup section installed `tree`
     cmd:     tree --version
     output:
       contains: ["Steve Baker", "Florian Sesser"]
   

3. Run tests for image

   java -jar docker-unittests.jar -f image-tests.yml -i openjdk:9.0.1-11

   

General image test with output to xml file

1. Use -o xml option in order to receive the testing report in xml format

   java -jar docker-unittests.jar -f image-tests.yml -i openjdk:9.0.1-11 -o xml

   

Test image by shell script

1. Define the test.yml with tests.

   version: 1.1
   
   tests:
   
     -  assume: "java version is 1.9, Debian build"
        cmd:    "java -version"
        output:
           contains:
            - openjdk version "9.0.1"
            - build 9.0.1+11-Debian
   
     # The test below will fail due to wrong version of curl.
     -  assume: "curl version is 8000"
        cmd:    "curl --version"
        output:
           startsWith: "curl 8000"
           matches:
             - "^curl\\s7.*\\n.*\\nProtocols.+ftps.+https.+telnet.*\\n.*\\n$"
           contains:
             - "AsynchDNS IDN IPv6 Largefile GSS-API"

2. Define an test.sh with testing command

   #!/usr/bin/env bash
   set -e
   echo Testing has been started
   java -jar docker-unittests.jar -f test.yml -i openjdk:9.0.1-11
   echo This line will not be executed as testing will fail

3. Run the test.sh

Output matching predicates
