# Allure Kotlin Integrations

The repository contains Allure2 adaptors for JVM-based test frameworks targeting Kotlin and Java with 1.6 source compatibility.

The core of this library was ported from `allure-java`. Thanks to that `allure-kotlin` has the same API, features, test coverage and solutions as `allure-java`. On top of the core library support for Kotlin and Android test frameworks were added.

Check out the [Allure Documentation][allure-docs].

## Supported frameworks
* JUnit4
* Android Robolectric (via AndroidX Test)
* Android Instrumentation (via AndroidX Test)

## Getting started

### JUnit4

#### Setting up the dependency
```gradle
repositories {
mavenCentral()
}

dependencies {
testImplementation "io.qameta.allure:allure-kotlin-model:$LATEST_VERSION"
testImplementation "io.qameta.allure:allure-kotlin-commons:$LATEST_VERSION"
testImplementation "io.qameta.allure:allure-kotlin-junit4:$LATEST_VERSION"
}
```
#### Attaching listener

Attach the `AllureJunit4` run listener using one of available methods:

- Attach the listener in build tool
- **Maven** - use [Maven Surfire Plugin][maven-surfire-plugin]
- **Gradle** - use [JUnit Foundation][junit-foundation] ([example][gradle-test-listener])
- Use predefined test runner

```kotlin
@RunWith(AllureRunner::class)
class MyTest {
...
}

@RunWith(AllureParametrizedRunner::class)
class MyParameterizedTest {
...
}
```

### Android tests

#### Setting up the dependency
```gradle
repositories {
mavenCentral()
}

dependencies {
androidTestImplementation "io.qameta.allure:allure-kotlin-model:$LATEST_VERSION"
androidTestImplementation "io.qameta.allure:allure-kotlin-commons:$LATEST_VERSION"
androidTestImplementation "io.qameta.allure:allure-kotlin-junit4:$LATEST_VERSION"
androidTestImplementation "io.qameta.allure:allure-kotlin-android:$LATEST_VERSION"
}
```

#### Attaching listener

AndroidX Test introduced a new `AndroidJUnit4` class runner that can be used for both **Robolectric** and **on-device instrumentation tests**. The same pattern is used for `AllureAndroidJUnit4` class runner. It attaches the allure listener to current class runner, but under the hood it uses `AndroidJUnit4`. All you need to do is to add `@RunWith(AllureAndroidJUnit4::class)` annotation to your test.

```kotlin
@RunWith(AllureAndroidJUnit4::class)
class MyInstrumentationTest {
...
}
```

Using AllureAndroidJUnit4 over class - works for both robolectric and on-device tests.

#### Robolectric tests

Robolectric tests are simple unit tests, hence the API is the same. The report data will be placed in the same place as for unit tests.

#### On-device instrumentation tests

You can also use testInstrumentationRunner for setting up runner.

```
android {
defaultConfig {
testInstrumentationRunner "io.qameta.allure.android.runners.AllureAndroidJUnitRunner"
}
}
```

##### Integration
As on-device instrumentation test run on an actual device, the results have to be saved there as well.
You don't need to add any permissions to manifest: results are saved in an app files directory, e.g.
`/data/data/com.example/files/allure-results`.

After the tests are finished you can move the results to the external storage and pull the files using an **adb** like this one:
```
# Assuming your package is com.example
adb exec-out run-as com.example sh -c 'cd /data/data/com.example/files && tar cf - allure-results' > allure-results.tar

# Or using pull
$ adb shell
$ run-as com.example sh -c 'cd /data/data/com.example/files && tar cf - allure-results' | tar xvf - -C /data/local/tmp
# Ignore the permission errors
$ exit
$ adb pull /data/local/tmp/allure-results
```
Finally, you can generate the report via Allure CLI (see the [Allure Documentation][allure-cli]) or generate report with [allure-gradle][allure-gradle-plugin] plugin.

##### **Orchestrator TestStorage**
When tests clears app data between each tests then saving test results in app storage will not work because old test results will be cleared when app data is cleared.
To save test results directly on sdcard new TestStorage from androidx.test.services can be used.

Enabling test storage for automation tests:
- add `allure.results.useTestStorage=true` to `allure.properties` in androidTest resources
- add `androidTestUtil("androidx.test:orchestrator:VERSION}` to your app dependencies (if you do not have it already)

After that allure will use TestStorage to save test results. Test results will be saved by default into `/sdcard/googletest/test_outputfiles/allure-results`
To get those files from device you can use e.g `adb exec-out sh -c 'cd /sdcard/googletest/test_outputfiles && tar cf - allure-results' | tar xvf - -C /output/dir`

*NOTE: allure-results folder name can be changed using `allure.results.directory` property.*

##### Features

The Allure Android API includes couple of features to make your reports a bit better.

###### Screenshot attachment

Screenshot can be taken and appended as an attachment to step or test in which they were executed:
```kotlin
@Test
fun screenshotExample() {
step("Step screenshot") {
allureScreenshot(name = "ss_step", quality = 90, scale = 1.0f)
}
allureScreenshot(name = "ss_test", quality = 50, scale = 1.0f)
}
```

###### Screenshot rule

Test rule to make the screenshot after each test and attach it to the test report. It includes a `mode` parameter which decides for which tests to make a screenshot:
* SUCCESS - only successful tests
* FAILURE - only failed tests
* END - all tests

```kotlin
@get:Rule
val logcatRule = ScreenshotRule(mode = ScreenshotRule.Mode.END, screenshotName = "ss_end")
```

###### Logcat rule

Test rule that clears the logcat before each test and appends the log dump as an attachment in case of failure.

```kotlin
@get:Rule
val logcatRule = LogcatRule()
```

###### Window hierarchy rule

You can use WindowHierarchyRule to capture a window hierarchy via uiautomator in case of Throwable during test.
```kotlin
@get:Rule
val windowHierarchyRule = WindowHierarchyRule()
```

## Samples

Different examples of `allure-kotlin` usage are presented in `samples` directory. This includes:
- `junit4-android` - complete Android sample with unit tests, robolectric tests and on device instrumentation tests

## Connection with allure-java

Following modules have been migrated:

* `allure-model` -> `allure-kotlin-model`
* `allure-java-commons` -> `allure-kotlin-commons`
* `allure-java-commons-test` -> `allure-kotlin-commons-test`

Following changes have to be made in order to keep the compatibility with Java 1.6:
* `java.util.Optional` (Java 1.8+) -> Kotlin null type & safe call operators
* `java.util.stream.*` (Java 1.8+) -> Kotlin collection operators
* `java.nio.file.*` (Java 1.7+) -> migrating form `Path` to `File`
* repeatable annotations (Java 1.8+) -> no alternatives, feature not supported by JVM 1.6

*The only part that was not migrated is aspects support.*
