Field Detail

tracks

protected java.util.List<TrackMetadataBean> tracks

Contains 30 test tracks.

strategy

protected IPlaylistStrategy strategy

The strategy instance being tested.

Constructor Detail

AbstractPlaylistStrategyTest

public AbstractPlaylistStrategyTest()

Method Detail

getStrategy

protected abstract IPlaylistStrategy getStrategy()

Returns the strategy instance.

Returns:

the strategy instance. The strategy playlist must be empty.

setUp

protected void setUp()
              throws java.lang.Exception

Overrides:

setUp in class junit.framework.TestCase

Throws:

java.lang.Exception

testEmptyPlaylist

public void testEmptyPlaylist()
                       throws java.lang.Exception

Throws:

java.lang.Exception

testAdding30Tracks

public void testAdding30Tracks()
                        throws java.lang.Exception

Throws:

java.lang.Exception

testQueuingTracks

public void testQueuingTracks()
                       throws java.lang.Exception

Throws:

java.lang.Exception

testPlayingQueuedTracks

public void testPlayingQueuedTracks()

assertNextTracks

protected void assertNextTracks(java.util.List<TrackMetadataBean> tracks,
                                boolean playlistEnd)

Asserts that next x tracks will be in same ordering as in the tracks list.

Parameters:

tracks - expect this ordering when playing next tracks.

playlistEnd - if true then the playlist must end after given tracks.

assertTracks

protected void assertTracks(java.util.List<java.lang.Integer> trackNumbers,
                            int startIndex)

Compares current strategy IPlaylistStrategy.getPlayItems() to tracks in tracks.

Parameters:

trackNumbers - indexes to the tracks list. null values are skipped.

startIndex - where to start

assertNextTracksUnordered

protected void assertNextTracksUnordered(java.util.List<TrackMetadataBean> tracks,
                                         boolean playlistEnd)

Asserts that next x tracks matches tracks in given tracks list. The number of tracks must match, however the track ordering is irrelevant (as opposed to assertNextTracks(List, boolean)).

Parameters:

tracks - expect these tracks when playing next tracks.

playlistEnd - if true then the playlist must end after given tracks.

verifyQueueProperties

protected void verifyQueueProperties(int expectedQueueLength)

Checks if the queue has correct queue count etc.

Parameters:

expectedQueueLength -

assertEquals

public static void assertEquals(java.util.List<? extends TrackMetadataBean> expected,
                                java.util.List<? extends PlaylistItem> actual)

Compares given track list with a playlist.

Parameters:

expected - the expected track list

actual - the playlist

assertEqualsQueue

protected void assertEqualsQueue(java.util.List<? extends TrackMetadataBean> expected)

Compares given track list with a playlist.

Parameters:

expected - the expected track list

assertEquals

public static void assertEquals(java.lang.Object[] expected,
                                java.util.List<?> actual)

Asserts that given list has given content.

Parameters:

expected -

actual -

testPlaySameTrack

public void testPlaySameTrack()

testNormalOrder

public void testNormalOrder()

public void testRemovingTracksPreservesCurrentlyPlayedTrack()

getCurrentlyPlaying

protected TrackMetadataBean getCurrentlyPlaying()

Returns strategy currently played track.

Returns:

never null. Fails if no track is being played.

testSetRandomModePreservesCurrentTrack

public void testSetRandomModePreservesCurrentTrack()
