Examples with Patch difflib.Patch used on opensource projects

Example 1 with Patch

use of difflib.Patch in project midpoint by Evolveum.

the class TestMigrator method assertSimpleMigration.

private <O extends ObjectType> void assertSimpleMigration(File fileOld, File fileNew) throws SchemaException, IOException {
    // GIVEN
    Migrator migrator = createMigrator();
    PrismContext prismContext = PrismTestUtil.getPrismContext();
    PrismObject<O> objectOld = prismContext.parseObject(fileOld);
    // WHEN
    PrismObject<O> objectNew = migrator.migrate(objectOld);
    // THEN
    IntegrationTestTools.display("Migrated object " + fileOld.getName(), objectNew);
    assertNotNull("No migrated object " + fileOld.getName(), objectNew);
    IntegrationTestTools.display("Migrated object " + fileOld.getName(), objectNew);
    String migratedXml = PrismTestUtil.serializeObjectToString(objectNew, PrismContext.LANG_XML);
    IntegrationTestTools.display("Migrated object XML " + fileOld.getName(), migratedXml);
    PrismObject<O> expectedObject = prismContext.parseObject(fileNew);
    IntegrationTestTools.display("Expected object " + fileOld.getName(), expectedObject);
    String expectedXml = PrismTestUtil.serializeObjectToString(expectedObject, PrismContext.LANG_XML);
    IntegrationTestTools.display("Expected object XML " + fileOld.getName(), expectedXml);
    List<String> expectedXmlLines = MiscUtil.splitLines(expectedXml);
    Patch patch = DiffUtils.diff(expectedXmlLines, MiscUtil.splitLines(migratedXml));
    List<String> diffLines = DiffUtils.generateUnifiedDiff(fileOld.getPath(), fileNew.getPath(), expectedXmlLines, patch, 3);
    IntegrationTestTools.display("XML textual diff", StringUtils.join(diffLines, '\n'));
    PrismAsserts.assertEquivalent("Unexpected migration result for " + fileOld.getName(), expectedObject, objectNew);
    assertEquals("Unexpected element name for " + fileOld.getName(), expectedObject.getElementName(), objectNew.getElementName());
}

Example 2 with Patch
