private boolean isCompressionEnabled(Session sess)

setupCompressionTest

@BeforeEach
public void setupCompressionTest()

teardownCompressionTest

@AfterEach
public void teardownCompressionTest()

compressionNegotiationServerSideRestricted

@Test
public void compressionNegotiationServerSideRestricted()

Tests compression negotiation, with compression algorithms restricted at server side.

compressionNegotiationClientSideSelectionNativelySupported

@Test
public void compressionNegotiationClientSideSelectionNativelySupported()

Tests compression negotiation with customized compression algorithms selections. "deflate_stream" is always selected as only "deflate_stream" is natively supported.

compressionNegotiationClientSideSelectionOtherThanNative

@Test
public void compressionNegotiationClientSideSelectionOtherThanNative()

Tests compression negotiation with customized compression algorithms selections, forcing the selection of a non-default algorithm (non-"deflate_stream"). Additional algorithms are enabled by using a fake InputStream. Creating the session fails because the InputStream is useless, but compression negotiation must succeed and an instance of the fake stream is created.

compressionNegotiationClientSideSelectionUnknownIds

@Test
public void compressionNegotiationClientSideSelectionUnknownIds()

Tests compression negotiation with customized compression algorithms selections, containing known and unknown algorithm identifiers.

compressionNegotiationClientSideSelectionNoCommon

@Test
public void compressionNegotiationClientSideSelectionNoCommon()

Tests compression negotiation with customized compression algorithms selections, with empty or only unknown algorithm identifiers.

compressionDisabled

@Test
public void compressionDisabled()

Tests compression disabled by connection option.

downlinkCompression

@Test
public void downlinkCompression()

Tests downlink compression using each one of the compression options.

uplinkCompression

@Test
public void uplinkCompression()

Tests uplink compression using each one of the compression options.

compressionThreshold

@Test
public void compressionThreshold()

Tests the compression threshold applied to uplink data.

invalidCompressionOptions

@Test
public void invalidCompressionOptions()

Tests invalid compression option values and returned error messages.

validCompressionExtensionsOption

@Test
public void validCompressionExtensionsOption()

Tests valid compression extensions option.

compressionNegotiationClientSideSelectionWithAliases

@Test
public void compressionNegotiationClientSideSelectionWithAliases()

Tests usage of compression algorithms aliases ("zstd", "lz4" and "deflate") on all places compression algorithms identifiers can be used.

testBug99708

@Test
public void testBug99708()

Test fix for Bug#99708 (31510398), mysql-connector-java 8.0.20 ASSERTION FAILED: Unknown message type: 57 s.close. This test is not entirely deterministic, since it depends on the size of the compressed data returned from the server. Observations showed that it fails in pretty close to 100% of executions. The test fails by throwing an exception.
