Release 1.4.0 (#32)
- Support for Android Gradle Plugin 4.1 (although version 1.3.0 also works fine with AGP 4.1). - Support for per module code coverage, generate a module specific report by running `./gradlew yourModule:coverageReport`. - New configuration option `includeNoLocationClasses` which (like the name implies) sets Jacoco's `includeNoLocationClasses`. This makes using the plugin in combination with Robolectric easier, since Robolectric often requires `includeNoLocationClasses` to be set to `true`. - The "Jacoco has been automatically applied" message is not longer a warning but now an info message.

# Android-Root-Coverage-Plugin
6-
**A Gradle plugin for combined code coverage reports for Android projects.**
7-
Generating code coverage reports for Android Projects is in most cases quite easy. Unfortunately by
8-
default (using Jacoco) code coverage is generated separately per module. This means each module
9-
takes into account it's own sources and tests (which is in terms of domain separation fine). However
10-
it is very common to find multi-module Android projects where only one module actually has tests.
11-
This plugin comes in handy for those projects. It generates code coverage reports using Jacoco
12-
taking into account all the modules and tests at once, or in other words: code in module B will show
13-
up as "covered" when tests in Module A touch it.
14-
15-
- Supports both Android app and library modules (`com.android.application` & `com.android.library`).
16-
- Supports different build variants per module within the same report.
17-
- Supports custom package/class filters.
6+
**Automatically configures Jacoco code coverage tasks for both combined and per module coverage reports.**
7+
8+
Configuring Jacoco for Android projects is unfortunately not always easy. It is very common to find multi-module Android
9+
projects where one module has tests for code found in another module, for example integration/UI tests that cover code
10+
in multiple other modules. Configuring Jacoco for such a case is not always straight forward, you need to point Jacoco
11+
to the right sources, execution data and class files, not to mention how error prone manual Jacoco setups can be. This
12+
plugin automatically configures Jacoco for you, so you don't have to.
13+
14+
**Feature highlights:**
15+
- Include unit-tests, instrumented unit-tests or both in the final reports
16+
- Support for combined coverage reports *(code in module X is covered when touched by tests from any other module)*
17+
- Support for coverage reports per module *(code in module X is only covered when touched by tests from module X)*
18+
- Custom package/class filters
19+
- Support for mixed build-types

# Setup

Apply the Android-Root-Coverage-Plugin plugin to your top-level (root project) gradle file:
4241
43-
```groovy
44-
// Step 2: Apply the plugin to the top-level gradle file
45-
apply plugin: 'nl.neotech.plugin.rootcoverage'
42+
# 1. Setup
43+
Apply the plugin to your top-level (root project) `build.gradle` file using one of the
44+
following methods:
4645
47-
buildscript {
48-
dependencies {
49-
// Step 1: add the dependency
50-
classpath 'nl.neotech.plugin:android-root-coverage-plugin:1.3.1'

# How to use
57-
Currently only modules with the plugin type `com.android.application` or `com.android.library` are
58-
taken into account when generating the coverage report, besides this any module that does not have
59-
`testCoverageEnabled true` for the selected build variant (by default: `debug`) will be skipped:
57+
<details>
58+
<summary><strong>classpath + apply:</strong></summary>
6059

61-
You can add a module by enabling `testCoverageEnabled`:
62-
```groovy
63-
android {
64-
buildTypes {
65-
debug {
66-
testCoverageEnabled true
67-
}
68-
}
60+
```groovy
61+
apply plugin: 'nl.neotech.plugin.rootcoverage'
62+
63+
buildscript {
64+
dependencies {
65+
classpath 'nl.neotech.plugin:android-root-coverage-plugin:1.4.0'
66+
}

}

```
68+

</details>

72-
The Android-Root-Coverage-Plugin generates a special Gradle task `:rootCodeCoverageReport` that when
73-
executed generates a Jacoco code coverage report. You can either run this task directly from
74-
Android Studio using the Gradle Tool Window (see:
75-
<https://www.jetbrains.com/help/idea/jetgradle-tool-window.html>) or from the terminal.

77-
- **Gradle Tool Window:** You can find the task under: `Tasks > reporting > rootCodeCoverageReport`, double click to execute it.
78-
- **Terminal:** Execute the task using `gradlew rootCodeCoverageReport`.

2. Run one of the automatically configured Gradle tasks to generate a Jacoco report:

99-
cause Jacoco instrumentation to fail in combination with inline kotlin methods shared across modules. For more information

By default the plugin generates code coverage reports using the build variant `debug` for every
106102
module. However in some cases different build variants per module might be required, especially if
107103
there is no `debug` build variant available. In those cases you can configure custom build variants
108104
for specific modules:
109105

110106
