Field Detail

DB

public static final CalciteAssert.DatabaseInstance DB

Which database to use for tests that require a JDBC data source. By default the test suite runs against the embedded hsqldb database.

We recommend that casual users use hsqldb, and frequent Calcite developers use MySQL. The test suite runs faster against the MySQL database (mainly because of the 0.1s versus 6s startup time). You have to populate MySQL manually with the foodmart data set, otherwise there will be test failures. To run against MySQL, specify '-Dcalcite.test.db=mysql' on the java command line.

ENABLE_SLOW

public static final boolean ENABLE_SLOW

Whether to enable slow tests. Default is false.

EMPTY_CONNECTION_FACTORY

public static final CalciteAssert.ConnectionFactory EMPTY_CONNECTION_FACTORY

Method Detail

that

public static CalciteAssert.AssertThat that()

Creates an instance of CalciteAssert with the empty configuration.

that

public static CalciteAssert.AssertThat that(CalciteAssert.Config config)

Creates an instance of CalciteAssert with a given configuration.

model

public static CalciteAssert.AssertThat model(String model)

Short-hand for CalciteAssert.that().with(Config.EMPTY).withModel(model).

hr

public static CalciteAssert.AssertThat hr()

Short-hand for CalciteAssert.that().with(Config.REGULAR).

checkResultCount

public static com.google.common.base.Function<ResultSet,Void> checkResultCount(org.hamcrest.Matcher<Integer> expected)

checkUpdateCount

public static com.google.common.base.Function<Integer,Void> checkUpdateCount(int expected)

checkResultContains

public static com.google.common.base.Function<ResultSet,Void> checkResultContains(String... expected)

checkResultContains

public static com.google.common.base.Function<ResultSet,Void> checkResultContains(String expected,
                                                                                  int count)

checkMaskedResultContains

public static com.google.common.base.Function<ResultSet,Void> checkMaskedResultContains(String expected)

checkResultType

public static com.google.common.base.Function<ResultSet,Void> checkResultType(String expected)

addSchema

public static SchemaPlus addSchema(SchemaPlus rootSchema,
                                   CalciteAssert.SchemaSpec schema)

assertArrayEqual

public static void assertArrayEqual(String message,
                                    Object[] expected,
                                    Object[] actual)

Asserts that two objects are equal. If they are not, an AssertionError is thrown with the given message. If expected and actual are null, they are considered equal.

This method produces more user-friendly error messages than Assert.assertArrayEquals(String, Object[], Object[])

Parameters:

message - the identifying message for the AssertionError (null okay)

expected - expected value

actual - actual value
