danger-shroud
A danger plugin for enforcing code coverage coverage via a Kover or Jacoco coverage report.
Installation
Add this line to your application's Gemfile:
gem 'danger-shroud'
Usage Kover
Shroud depends on having a Kover coverage report generated for your project. For Android projects, kotlinx-kover works well.
Parameters
You can use the following parameters to control how shroud operates:
Param | Type | Description | Example |
---|---|---|---|
moduleName | String | the display name of the project or module. | 'Module Name ' |
file | String | file path to a Kover xml coverage report. | 'path/to/kover/report.xml' |
totalProjectThreshold | Integer | defines the required percentage of total project coverage for a passing build. | default 90
|
modifiedFileThreshold | Integer | defines the required percentage of files modified in a PR for a passing build. | default 90
|
failIfUnderProjectThreshold | Boolean | if true, will fail builds that are under the provided thresholds. if false, will only warn. | default true
|
failIfUnderFileThreshold | Boolean | if true, will fail builds that are under the provided thresholds. if false, will only warn. | default true
|
Examples
Running shroud with default values:
# Report coverage of modified files, fail if either total
# project coverage or any modified file's coverage is under 90%
shroud.reportKover moduleName: 'Module Name', file: 'path/to/kover/report.xml'
Running shroud with custom coverage thresholds:
# Report coverage of modified files, fail if total project coverage is under 80%,
# or if any modified file's coverage is under 95%
shroud.reportKover moduleName: 'Module Name', file: 'path/to/kover/report.xml', totalProjectThreshold: 80, modifiedFileThreshold: 95
Warn on builds instead of fail:
# Report coverage of modified files the same as the above example, except the
# builds will only warn instead of fail if below project thresholds
shroud.reportKover moduleName: 'Module Name', file: 'path/to/kover/report.xml', totalProjectThreshold: 80, modifiedFileThreshold: 95, failIfUnderProjectThreshold: false, failIfUnderFileThreshold: false
Usage Jacoco
Parameters
You can use the following parameters to control how shroud operates:
Param | Type | Description | Example |
---|---|---|---|
moduleName | String | the display name of the project or module. | 'Module Name ' |
file | String | file path to a Jacoco xml coverage report. | 'path/to/jacoco/report.xml' |
totalProjectThreshold | Integer | defines the required percentage of total project coverage for a passing build. | default 90
|
modifiedFileThreshold | Integer | defines the required percentage of files modified in a PR for a passing build. | default 90
|
failIfUnderProjectThreshold | Boolean | if true, will fail builds that are under the provided thresholds. if false, will only warn. | default true
|
failIfUnderFileThreshold | Boolean | if true, will fail builds that are under the provided thresholds. if false, will only warn. | default true
|
Examples
Shroud depends on having a Jacoco coverage report generated for your project. For Android projects, jacoco-android-gradle-plugin works well.
Running shroud with default values:
# Report coverage of modified files, fail if either total
# project coverage or any modified file's coverage is under 90%
shroud.reportJacoco moduleName: 'Module Name', file: 'path/to/jacoco/report.xml'
Running shroud with custom coverage thresholds:
# Report coverage of modified files, fail if total project coverage is under 80%,
# or if any modified file's coverage is under 95%
shroud.reportJacoco moduleName: 'Module Name', file: 'path/to/jacoco/report.xml', totalProjectThreshold: 80, modifiedFileThreshold: 95
Warn on builds instead of fail:
# Report coverage of modified files the same as the above example, except the
# builds will only warn instead of fail if below thresholds
shroud.reportJacoco moduleName: 'Module Name', file: 'path/to/jacoco/report.xml', totalProjectThreshold: 80, modifiedFileThreshold: 95, failIfUnderProjectThreshold: false, failIfUnderFileThreshold: false
