TheFonz2017 41dcebb3a5 Variable Substitution in YAML Files (#852)
* Changes:
- New YamlSubstituteVariables step to substitute variables in YAML files with values from another YAML
- New Tests, that check the different substitution patterns.
- Added test resources, including various manifest and variables files.
- Improved usage of JenkinsLoggingRule
- Improved JenkinsReadYamlRule to properly reflect the mocked library's behaviour.
- Added a new JenkinsWriteYamlRule.

* Changes:
- added a Logger that checks a config.verbose flag before it logs debug messages.
- changed error handling to rethrow Yaml parsing exception in case of wrongly-formatted Yaml files.
- changed JenkinsWriteYamlRule to capture Yaml file details of every invocation of writeYaml. This allows sanity checks at end of tests, even if there were multiple invocations.
- adjusted tests.

* Changes:
- Removed javadoc-code blocks from API documentation since they are not supported.
- Removed skipDeletion boolean.
- Added a new deleteFile script which deletes a file if present.
- Added a new JenkinsDeleteFileRule to mock deleteFile script and optionally skip deletion for tests.
- Adjusted yamlSubstituteVariables script.
- Adjusted tests to include new JenkinsDeleteFileRule.
- Changed code that deletes an already existing output file to produce better logs.

* Changes:
- Turned yamlSubstituteVariables into a script that works purely based on Yaml data (not files).
- Added a new cfManifestSubstituteVariables that uses yamlSubstituteVariables under the hood but works based on files.
- Adjusted tests, and added new ones.

* Adjusted documentation and a few log statements.

* Changed documentation to no longer include javadoc code statements.

* Made mocking of deletion of a file a default. Adjusted tests.

* Changed signature of yamlSubstituteVariables' call method to return void.

* Changes:
- Fixed naming issues in deleteFile.
- Renamed Logger to DebugHelper.
- Fixed some documentation.

* Changed implementation of deleteFile not to use java.io.File - which is evil when using it for file operations.

* PROPERLY Changed implementation of deleteFile not to use java.io.File - which is evil when using it for file operations.

* Changes:
- Added tests for deleteFile script
- Changed JenkinsFileExistsRule to also keep track of which files have been queried for existence.

* Changes:
- Removed java.io.File usage from cfManifestSubstituteVariables and using fileExists instead now.
- Adjusted tests.

* Wrapped file path inside ticks to allow spaces in file path when calling deleteFile.

* Removed null checks of mandatory parameters, and resorted to ConfigurationHelper.withMandatoryProperty

* Fixed a NullPointer due to weird Jenkins / Groovy behaviour.

* Changes:
- Turned yamlSubstituteVariables step into a utils class.
- Added tests
- Adjusted cfManifestSubstituteVariables to use utils class instead of step.
- Adjusted tests
- Adjusted APIs of DebugHelper.

* Re-introduced log statement that shows what variables are being replaced and with what.

* Changing API of YamlUtils to take the script and config as input.

* Test

* Test

* Test

* Test

* Test

* Fixing issue.

* Fixing issue.

* Changes:
- Refactored DebugHelper and YamlUtils to make usage nicer and rely on dependency injection.
- Removed Field for DebugHelper and turned it into local variable.
- Adjusted classes using the above.
- Adjusted tests where necessary.

* Added link to CF standards to YamlUtils also.

* Add docu for step cfManifestSubstituteVariables.md

* Added documentation.

* Added missing script parameter to documentation. Some steps document it, some don't. Right now you need it, so we document it.

* Fixed some layouting and typos

* Beautified exception listing.

* Removed trailing whitespaces to make code climate checks pass.

* Trying to get documentation generated, with all the exceptions to markup one should not use.

* cosmetics.

* cosmetics, part 2

* Code climate changes...

* Inlined deleteFile step.

* Added two more tests to properly check file deletion and output handling.

* Changes:
- adjusted API to take a list of variables files, as does 'cf push --vars-file'
- adjusted API to allow for an optional list of variable key-value-maps as does 'cf push --vars'
- reproduced conflict resolution and overriding behavior of variables files and vars lists
- adjusted tests and documentation

* Added missing paramter to doc comment.

* Re-checked docs for missing paramters or params that have no counterpart in the method signature.

* Adjusted documentation.

* Removed absolute path usage from documentation.

* corrected documentation.

* Changed javadoc comment to plain comment.

* Turned all comments to plain comments.
