Example 1 with EmptyReader

use of org.openstreetmap.osmosis.core.misc.v0_6.EmptyReader in project osmosis by openstreetmap.

the class ChangeDeriverTest method rightEmpty.

/**
 * Deriving change with an empty right input should yield
 * a change with creates only.
 *
 * @throws Exception if something goes wrong.
 */
@Test
public void rightEmpty() throws Exception {
    // Cannot be tested with file comparison as the derived
    // change contains deletes which have a current timestamp
    // that cannot be reliably predicted.
    // Therefore, check all relevant attributes manually.
    ChangeDeriver deriver = new ChangeDeriver(1);
    RunnableSource left = new XmlReader(dataUtils.createDataFile("v0_6/derive_change/simple.osm"), true, CompressionMethod.None);

Example 2 with EmptyReader

use of org.openstreetmap.osmosis.core.misc.v0_6.EmptyReader in project osmosis by openstreetmap.

the class EntityMergerTest method mergeAndLookForException.

/**
 * Runs a merge and records the exceptions that happened during the merge.
 *
 * The test is considered passed iff at least one exception was thrown and
 * the exception message begins with a given string.
 *
 * This method does not use command line parsing because it is impossible
 * to check whether the right exception has been thrown. Also, as all
 * exceptions are OsmosisRuntimeExceptions, we need to check the message
 * so the JUnit expected exception facility is no good here.
 *
 * To add insult to injury, running a merge task involves three worker threads;
 * the exception we expect is thrown on one of those worker threads which brings
 * the pipeline down. But we want to check for that one source exception
 * is thrown for the correct reason, otherwise the test becomes very unspecific.

Example 3 with EmptyReader
