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. [Additional details about com.slack.lint:slack-lint-checks](com_slack_lint_slack-lint-checks.md.html). (##) 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).
