Example 16 with FileWriter

use of java.io.FileWriter in project hadoop by apache.

the class TestConfiguration method testPattern.

public void testPattern() throws IOException {
    out = new BufferedWriter(new FileWriter(CONFIG));
    startConfig();
    appendProperty("test.pattern1", "");

    endConfig();
    Path fileResource = new Path(CONFIG);
    conf.addResource(fileResource);
    Pattern defaultPattern = Pattern.compile("x+");
    // Return default if missing
    assertEquals(defaultPattern.pattern(), conf.getPattern("xxxxx", defaultPattern).pattern());
    // Return null if empty and default is null
    assertNull(conf.getPattern("test.pattern1", null));
    // Return default for empty
    assertEquals(defaultPattern.pattern(), conf.getPattern("test.pattern1", defaultPattern).pattern());
    // Return default for malformed
    assertEquals(defaultPattern.pattern(), conf.getPattern("test.pattern2", defaultPattern).pattern());
    // Works for correct patterns
