A JUnit rule which allows unit testing of custom Lint rules.

lint-junit-rule's Issues

Increase test coverage

Android Studio cannot find files under test/resource directory

Fixed on #16

Add sample

Showcase usage of this rule.
Emphasize standard approach vs. JUnit4 approach.

Could not resolve v0.3.0

In our project, it's fail to resolve this library from jcenter

There seems no jars in jcenter. Check this https://jcenter.bintray.com/de/ad/

Could you upload jar file? or am I missing something?

Thanks in advance.

Add assertj assertion

Evaluate new lint-test library

https://android.googlesource.com/platform/tools/base/+/4065f99c18aec7bc9519b74f00ebc6dfb22920f1

Add hamcrest matcher

Add inline declaration of test resources

The standard LintDetectorTest features two approaches to load test resources:

• lintFiles and
• lintProject

While the first approach is already covered by lint-junit-rule it would be convenient to also feature the second approach in order to allow inline declaration of test resources.

Sample test cases for .java file?

Could you give me a sample test case for .java file?

@RunWith(JUnit4.class)
public class LintTestCase extends TestCase {

    @Rule
    public Lint lint = new Lint(new PermissionDispatcherDetector(), PermissionDispatcherDetector.ISSUE);

    @Test
    public void testFoo() throws Exception {
        List<Warning> lintResult = lint.files("MainActivity.java");
        assertThat(lintResult).hasWarnings(1).in("MainActivity.java");
    }
}

This code does not work since it claims there is no MainActivity.java, so changed it to

@RunWith(JUnit4.class)
public class LintTestCase extends TestCase {

    @Rule
    public Lint lint = new Lint(new PermissionDispatcherDetector(), PermissionDispatcherDetector.ISSUE);

    @Test
    public void testFoo() throws Exception {
-        List<Warning> lintResult = lint.files("MainActivity.java");
+        List<Warning> lintResult = lint.files("MainActivity.class");
        assertThat(lintResult).hasWarnings(1).in("MainActivity.java");
    }
}

And now it run the test case. However, I want to test the lint for MainActivity.java not MainActivity.class because .java file contains annotations with @Retention(RetentionPolicy.SOURCE) which is deleted in .class in compile time.

Thanks in advance.
