示例1: test
test(`json and arrow buffers report the same values`, () => {
expect.hasAssertions();
const jsonVectors = toArray(read(jsonData));
const binaryVectors = toArray(read(arrowBuffers));
for (const [jVectors, bVectors] of zip(jsonVectors, binaryVectors)) {
expect(jVectors.length).toEqual(bVectors.length);
for (let i = -1, n = jVectors.length; ++i < n;) {
(expect(jVectors[i]) as any).toEqualVector(bVectors[i]);
}
}
});示例2: test
test(`json and arrow record batches report the same values`, () => {
expect.hasAssertions();
const jsonRecordBatches = toArray(read(jsonData));
const binaryRecordBatches = toArray(read(arrowBuffer));
for (const [jsonRecordBatch, binaryRecordBatch] of zip(jsonRecordBatches, binaryRecordBatches)) {

expect(jsonRecordBatch.numCols).toEqual(binaryRecordBatch.numCols);
for (let i = -1, n = jsonRecordBatch.numCols; ++i < n;) {
