Classes

MockDataConnection

A class to mock google::cloud::bigtable::DataConnection.

Functions

MakeRowReader(std::vector< bigtable::Row >, Status)

Returns a RowReader with a fixed output stream.

This factory function is offered for customers to mock the output of Table::ReadRows(...) in their tests.

Note: If Cancel() is called on the RowReader, the stream will terminate and return final_status.

TEST(ReadRowsTest, Success) {
  using ::google::cloud::StatusOr;
  using cbt = ::google::cloud::bigtable;
  using cbtm = ::google::cloud::bigtable_mocks;

  std::vector<cbt::Row> rows = {cbt::Row("r1", {}), cbt::Row("r2", {})};

  auto mock = std::shared_ptr<cbtm::MockDataConnection>();
  EXPECT_CALL(*mock, ReadRowsFull)
      .WillOnce(Return(cbtm::MakeRowReader(rows)));

  auto table = cbt::Table(mock);
  auto reader = table.ReadRows(...);

  // Verify your code works when reading rows: {"r1", "r2"}
}

Parameters
Name	Description
rows	a vector containing the Rows returned by iterating over the RowReader.
final_status	the final Status of the stream. Defaults to OK.
