方法详细资料

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 Consumer<ResultSet> checkResultCount(org.hamcrest.Matcher<Integer> expected)

checkUpdateCount

public static Consumer<Integer> checkUpdateCount(int expected)

checkResultContains

public static Consumer<ResultSet> checkResultContains(String... expected)

checkResultContains

public static Consumer<ResultSet> checkResultContains(String expected,
                                                      int count)

checkMaskedResultContains

public static Consumer<ResultSet> checkMaskedResultContains(String expected)

checkResultType

public static Consumer<ResultSet> checkResultType(String expected)

toString

public static String toString(ResultSet resultSet)
                       throws SQLException

Converts a ResultSet to a string.

抛出:

SQLException

addSchema

public static org.apache.calcite.schema.SchemaPlus addSchema(org.apache.calcite.schema.SchemaPlus rootSchema,
                                                             CalciteAssert.SchemaSpec... schemas)

Adds a schema specification (or specifications) to the root schema, returning the last one created.

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 Assertions.assertArrayEquals(Object[], Object[], String)

参数:

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

expected - expected value

actual - actual value
