Class CheckerFrameworkPerDirectoryTest

java.lang.Object

org.checkerframework.framework.test.CheckerFrameworkPerDirectoryTest

public abstract class CheckerFrameworkPerDirectoryTest
extends Object

Compiles all test files in a test directory together. Use CheckerFrameworkPerFileTest to compile each test file in a test directory individually. A CheckerFrameworkPerDirectoryTest is faster than an equivalent CheckerFrameworkPerFileTest, but can only test that processor errors or warnings are issued.

To create a CheckerFrameworkPerDirectoryTest, create a new class that extends this class. The new class must do the following:

1. Declare a constructor taking 1 parameter of type java.util.List<java.io.File>. This is a list of the files that will be compiled.
2. Declare the following method:

    @Parameters public static String [] getTestDirs()

   getTestDir must return an array of directories that exist in the test folder. The directories can contain more path information (e.g., "myTestDir/moreTests") but note, the test suite will find all of the Java test files that exists below the listed directories. It is unnecessary to list child directories of a directory you have already listed.

 public class MyTest extends CheckerFrameworkPerDirectoryTest {
   public MyTest(List<File> testFiles) {
     super(testFiles, MyChecker.class, "", "Anomsgtext");
   }
   {@literal @}Parameters
   public static String [] getTestDirs() {
     return new String[]{"all-systems"};
   }
 }

Field Detail

testFiles

protected final List<File> testFiles

checkerName

protected final String checkerName

The fully-qualified class name of the checker to use for tests.

testDir

protected final String testDir

The path, relative to currentDir/test to the directory containing test inputs.

Constructor Detail

CheckerFrameworkPerDirectoryTest

public CheckerFrameworkPerDirectoryTest(List<File> testFiles,
                                        Class<? extends AbstractProcessor> checker,
                                        String testDir,
                                        String... checkerOptions)

Creates a new checker test.

TestConfigurationBuilder.getDefaultConfigurationBuilder(String, File, String, Iterable, Iterable, List, boolean) adds additional checker options such as -AprintErrorStack.

Parameters:

checker - the class for the checker to use

testDir - the path to the directory of test inputs

checkerOptions - options to pass to the compiler when running tests

Method Detail

run

public void run()

customizeOptions

public List<String> customizeOptions(List<String> previousOptions)

Override this method if you would like to supply a checker command-line option that depends on the Java files passed to the test. Those files are available in field testFiles.

If you want to specify the same command-line option for all tests of a particular checker, then pass it to the CheckerFrameworkPerDirectoryTest(java.util.List<java.io.File>, java.lang.Class<? extends javax.annotation.processing.AbstractProcessor>, java.lang.String, java.lang.String...) constructor.

Parameters:

previousOptions - the options specified in the constructor of the test previousOptions is unmodifiable

Returns:

a new list of options or the original passed through
