What is it?

Westie is a tool for creating your own custom static analysis checks.

The project contains already provided checks which can be used straight away.

All provided Analysers utilise WestieAnalyser.java, which is the entrypoint to a fluent API with useful functions for creating your own static analysis checks for your team, on your projects.

For documentation on writing your own static analysis checks, see the documentation.

Examples of provided static analysis analysers:

EnvironmentPropertiesAnalysers ensures that all of your environment '.properties' files share the same keys.

@Test
public void allEnvironmentPropertiesFilesHaveTheSameKeys() throws Exception {
    List<FileViolation> violations = new EnvironmentPropertiesAnalyser()
            .propertiesProvidedForAllEnvironments(PROPERTIES_DIR);

    assertThat(violations).isEmpty();
}

No more forgetting to add a url to all your environment's configurations. Your build will instead fail.

JiraReferenceAnalyser ensures that Jira issues referenced are in an accepted status (e.g only in Development stage).

@Test
public void canOnlyReferenceJiraIssuesInDevelopment() throws Exception {
    List<Violation> violations = new JiraReferenceAnalyser(jiraIssues, JIRA_STORY_REGEX)
            .todosAreInAllowedStatuses(BASE_PACKAGE);

    assertThat(violations).isEmpty();
}

// below is part of 'JiraReferenceAnalyser.java'
public List<Violation> todosAreInAllowedStatuses(Path pathToCheck, List<String> filesToIgnore) throws IOException {
    return westieAnalyser.analyseDirectory(pathToCheck)
            .forJavaFiles().ignoring(filesToIgnore)
            .analyseLinesOfFile(this::checkJiraTodos, format("Violation was caused by a reference to a " +
                    "Jira issue which is not in any of the accepted statuses: '%s'.", jiraIssues.allowedStatuses()));
}

private boolean checkJiraTodos(String fileLine) {
    return isJiraTodoLine(fileLine) && jiraIssueInUnacceptedState(fileLine);
}
...

No more forgetting to complete TODOs as part of your Jira story. Your build will instead fail. The same can be done for Git Issues.
