Example 1 with Serializer

use of org.finos.legend.engine.plan.execution.result.serialization.Serializer in project legend-engine by finos.

the class TestJsonStreamingResult method doesNotAutocloseJsonArrays.

private void doesNotAutocloseJsonArrays(SerializationFormat format) throws Exception {
    JsonStreamingResult result = new JsonStreamingResult(x -> {
        try {
            x.writeStartArray();
            // throw before closing array to mimic streaming error
            throw new TestException();
        } catch (IOException e) {
            throw new UncheckedIOException(e);
        }

        serializer.stream(outputStream);
    } catch (TestException e) {
        try {
            new ObjectMapper().readTree(outputStream.toByteArray());
            Assert.fail("Serialized bytes should not contians valid JSON.  Is Jackson autoclosing arrays and objects?");
        } catch (JsonEOFException eofException) {
            assertThat(eofException, hasMessage(CoreMatchers.startsWith("Unexpected end-of-input: expected close marker for Array")));
