# Changelog
All notable changes to the Code Coverage package will be documented in this file.

The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).

## [1.2.3] - 2023-04-14

### Fixes
- Fixed failing to gather code coverage for generic methods (case [COV-17](https://issuetracker.unity3d.com/issues/coverage-package-fails-to-gather-any-coverage-for-generic-methods)).

### Improvements
- Added `filtersFromFile` in *-coverageOptions* for [batchmode](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/CoverageBatchmode.html). This allows specifying an external Json file which contains path and assembly filtering rules. When this file contains relative paths, the `sourcePaths` option can be used to specify the source directories.
<br/>**Note:** The `pathFiltersFromFile` option will be deprecated in the next package major release. Please use the new `filtersFromFile` option instead.
- Make sure `--burst-disable-compilation` is [expected](https://docs.unity3d.com/Packages/com.unity.burst@latest/index.html?subfolder=/manual/getting-started.html#command-line-options) to be passed with two dashes, unlike other editor command line options. 

## [1.2.2] - 2022-11-18

### Fixes
- Temporary fix for the [Test Framework](https://docs.unity3d.com/Packages/com.unity.test-framework@latest/index.html) 1.3 issue where the *RunFinished* callback is not called when running from the command line and there is a domain reload (case [DSTR-692](https://issuetracker.unity3d.com/issues/registered-callbacks-dont-work-after-domain-reload)).

### Improvements
- Reduced the number of logs for the default *Verbosity:Info*.
- Added *Uncoverable lines* definition in [How to interpret the results](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/HowToInterpretResults.html#summary) page in the documentation.
- Updated documentation to match version 1.2.2.

## [1.2.1] - 2022-10-27

### Fixes
- Fixed compatibility with [Test Framework](https://docs.unity3d.com/Packages/com.unity.test-framework@latest/index.html) package version 1.3.

### Improvements
- A single file summary version of the report is now generated in Json format, in addition to the XML and Markdown formats.
- Added a warning when an invalid coverage option is passed in *-coverageOptions* in [batchmode](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/CoverageBatchmode.html).

## [1.2.0] - 2022-08-01

### Fixes
- Ensure assemblies are removed from the Included Assemblies field if they no longer exist (case [1318668](https://issuetracker.unity3d.com/issues/code-coverage-the-included-assemblies-field-shows-assemblies-that-no-longer-exist)).
- Ensure hidden sequence points are ignored (case [1372305](https://issuetracker.unity3d.com/issues/class-which-derives-from-methodbase-causes-incorrect-sequence-points-to-be-generated-by-coverage-api)).

### Changes
- Updated Report Generator to version 5.0.4.
- Updated the UI of the [Code Coverage window](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/CodeCoverageWindow.html) moving the action buttons into a toolbar at the top.
- Renamed *assemblyFilters* aliases in [batchmode](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/CoverageBatchmode.html); `<user>` was renamed to `<assets>` and `<project>` was renamed to `<all>`.
- Replaced `pathStrippingPatterns` with `pathReplacePatterns` in [batchmode](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/CoverageBatchmode.html). The `pathReplacePatterns` option allows stripping and replacing specific sections from the paths that are stored in the coverage results xml files.

See the [Upgrade guide](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/upgrade-guide.html) if upgrading to Code Coverage package version 1.2.

### Improvements
- The size of the coverage result files and the Code Coverage session duration have been optimized. At the start of the session a coverage xml result file is generated which includes all the lines but with zero coverage. The following coverage xml result files that are generated within a Code Coverage session include only the coverage data of the visited lines.
- Added Help IconButton in the toolbar in the [Code Coverage window](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/CodeCoverageWindow.html).
- Updated the mechanic for opening the containing folder, change the location or reset to the default location for *Results Location* and *Report History Location*.
- Refactored the [Code Coverage window](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/CodeCoverageWindow.html) UI to include a new *Report Options* section and removing the word 'Generate' from the options.
- Introduced new selection buttons under the *Included Assemblies* dropdown in the [Code Coverage window](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/CodeCoverageWindow.html); use the *All* button to select all the assemblies in the project. Use the *Assets* button to select only the assemblies under the `Assets` folder. Use the *Packages* button to select only the Packages' assemblies. If searching, the buttons will apply only to the assemblies visible in the list.
- Updated [What's new](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/whats-new.html) and [Upgrade guide](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/upgrade-guide.html) pages in the documentation.
- Added [Using relative paths in path filters](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/CoverageBatchmode.html#using-relative-paths-in-path-filters) section in documentation.
- Updated the editor and console logs; added information about the assembly and path filters, improved coverage session logs.
- Improved the progress bars for `Writing coverage results` and `Generating the report`.
- Added an icon for the [Code Coverage window](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/CodeCoverageWindow.html).
- Updated documentation to match version 1.2.0.

Added `generateAdditionalReports` in *-coverageOptions* for [batchmode](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/CoverageBatchmode.html).
- Added `Test Runner References` report option in the [Code Coverage window](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/CodeCoverageWindow.html) which if checked includes test references to the generated coverage results and enables the [Coverage by test methods](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/HowToInterpretResults.html#coverage-by-test-methods) section in the HTML report, allowing you to see how each test contributes to the overall coverage. Added `generateTestReferences` in *-coverageOptions* for [batchmode](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/CoverageBatchmode.html).
- Added `Auto Open Report` option in the [Code Coverage window](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/CodeCoverageWindow.html) which if checked the coverage report will open automatically after it has been generated.
- Added `pathFiltersFromFile` in *-coverageOptions* for [batchmode](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/CoverageBatchmode.html) which allows specifying an external file which contains a list of path filters. When this file contains relative paths, the `sourcePaths` option can be used to specify the source directories.
- Added `dontClear` in *-coverageOptions* for [batchmode](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/CoverageBatchmode.html) which allows coverage results to be accumulated after every code coverage session. If not passed the results are cleared before a new session. For more information see [Generate combined report from EditMode and PlayMode tests](https://docs.unity3d.com/Packages/com.unity.testtools.codecoverage@1.2/manual/CoverageBatchmode.html#generate-combined-report-from-editmode-and-playmode-tests).
- When the `pathFilters` option or the `pathFiltersFromFile` option in *-coverageOptions* contains relative paths, the `sourcePaths` option can be used to specify the source directories.
