Starting point for that refactoring: it turned out that the tests
was not independent. The DefaultValueCache which is a singleton
keeps the status over various tests. Success of test execution depends
on the order test execution.
We have now
* a dedicated rule for resetting the default value cache
* JenkinsConfiguration rule (which already provided facilities for
dealing with the configuration) has been replaced by a readYaml rule.
From the PipelineUnit test framework we get already a handler for
libraryResource, which is also part of the setup of the default
values.
* An auxiliar class which combines the
* JenkinsSetupRule (registers the lib)
* JenkinsReadYamlRule (provides facilities for Yaml parsing)
* JenkinsResetDefaultValueCacheRule (cleans up the DefaultValueCache)
into a rule chain. By using this rule chain we ensure that our
setup OK (piper lib registered, and default config can be setup in
a clean way).
Before this commit the fileExists mock was not doing the same as the
real fileExists method. To stay close to reality we changed it construct
the absolute path and check for that when the fileExists method is
called.
Refactored to archiveName instead of archivePath, as this makes more
sense now.
When running on a slave we have to use the Pipeline method fileExists,
using the File class' exist on the absolute path fails.
The neo deployment uses the relative path as well.
The fileExists method is mocked with LesFurets.
We check
1.) if docker-workflow plugin is installed
2.) if docker itself is installed on the system hosting Jenkins
If one of the conditions is not fullfilled we try to execute
locally.
node() is not necessary in the LesFurets unit tests. This is especially
misleading for the pipelineExecute step, as the step itself opens a node
closure when loading a pipeline. If used like this in Jenkins
unnecessary executors will be used.
