`AutoValue` classes represent pure data classes, so mocking them should
not be necessary. Construct a real instance of the class instead.
(##) Options
You can configure this lint checks using the following options:
(###) mock-annotations
A comma-separated list of mock annotations..
This property should define comma-separated list of mock annotation class names (FQCN). Set this for all issues using this option.
Default is "org.mockito.Mock,org.mockito.Spy".
Example `lint.xml`:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~xml linenumbers
<lint>
<issue id="DoNotMockAutoValue">
<option name="mock-annotations" value=""org.mockito.Mock,org.mockito.Spy"" />
</issue>
</lint>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
(###) mock-factories
A comma-separated list of mock factories (org.mockito.Mockito#methodName)..
A comma-separated list of mock factories (org.mockito.Mockito#methodName). Set this for all issues using this option.
Default is "org.mockito.Mockito#mock,org.mockito.Mockito#spy,slack.test.mockito.MockitoHelpers#mock,slack.test.mockito.MockitoHelpersKt#mock,org.mockito.kotlin.MockingKt#mock,org.mockito.kotlin.SpyingKt#spy".
Example `lint.xml`:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~xml linenumbers
<lint>
<issue id="DoNotMockAutoValue">
<option name="mock-factories" value=""org.mockito.Mockito#mock,org.mockito.Mockito#spy,slack.test.mockito.MockitoHelpers#mock,slack.test.mockito.MockitoHelpersKt#mock,org.mockito.kotlin.MockingKt#mock,org.mockito.kotlin.SpyingKt#spy"" />
</issue>
</lint>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
(###) mock-report
If enabled, writes a mock report to /build/reports/mockdetector/mock-report.csv..
If enabled, writes a mock report to /build/reports/mockdetector/mock-report.csv. The format of the file is a csv of (type,isError) of mocked classes. Set this for all issues using this option.
Default is "none".
Example `lint.xml`:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~xml linenumbers
<lint>
<issue id="DoNotMockAutoValue">
<option name="mock-report" value=""none"" />
</issue>
</lint>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
(##) Including
!!!
This is not a built-in check. To include it, add the below dependency
to your project. This lint check is included in the lint documentation,
but the Android team may or may not agree with its recommendations.
```
// build.gradle.kts
lintChecks("com.slack.lint:slack-lint-checks:0.9.0")
// build.gradle
lintChecks 'com.slack.lint:slack-lint-checks:0.9.0'
// build.gradle.kts with version catalogs:
lintChecks(libs.slack.lint.checks)
# libs.versions.toml
[versions]
slack-lint-checks = "0.9.0"
[libraries]
# For clarity and text wrapping purposes the following declaration is
# shown split up across lines, but in TOML it needs to be on a single
# line (see https://github.com/toml-lang/toml/issues/516) so adjust
# when pasting into libs.versions.toml:
slack-lint-checks = {
module = "com.slack.lint:slack-lint-checks",
version.ref = "slack-lint-checks"
}
```
0.9.0 is the version this documentation was generated from;
there may be newer versions available.

(##) Suppressing
You can suppress false positives using one of the following mechanisms:
* Using a suppression annotation like this on the enclosing
element:
```kt
// Kotlin
@Suppress("DoNotMockAutoValue")
fun method() {
problematicStatement()
}
```
or
```java
// Java
@SuppressWarnings("DoNotMockAutoValue")
void method() {
problematicStatement();
}
```
* Using a suppression comment like this on the line above:
```kt
//noinspection DoNotMockAutoValue
problematicStatement()
```
* Using a special `lint.xml` file in the source tree which turns off
the check in that folder and any sub folder. A simple file might look
like this:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<lint>
<issue id="DoNotMockAutoValue" severity="ignore" />
</lint>
```
Instead of `ignore` you can also change the severity here, for
example from `error` to `warning`. You can find additional
documentation on how to filter issues by path, regular expression and
so on
[here](https://googlesamples.github.io/android-custom-lint-rules/usage/lintxml.md.html).
* In Gradle projects, using the DSL syntax to configure lint. For
example, you can use something like
```gradle
lintOptions {
disable 'DoNotMockAutoValue'
}
```
In Android projects this should be nested inside an `android { }`
block.
* For manual invocations of `lint`, using the `--ignore` flag:
```
$ lint --ignore DoNotMockAutoValue ...`
```
* Last, but not least, using baselines, as discussed
[here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
