Examples with ByteArrayOutputStream java.io.ByteArrayOutputStream used on opensource projects

Example 46 with ByteArrayOutputStream

use of java.io.ByteArrayOutputStream in project bazel by bazelbuild.

the class ZipCombinerTest method testUncompressedForceDeflate.

@Test
public void testUncompressedForceDeflate() throws IOException {
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    try (ZipCombiner zipCombiner = new ZipCombiner(OutputMode.FORCE_DEFLATE, out)) {
        zipCombiner.addZip(sampleZipWithOneUncompressedEntry());
    }
    FakeZipFile expectedResult = new FakeZipFile().addEntry("hello.txt", "Hello World!", true);
    expectedResult.assertSame(out.toByteArray());
}

Example 47 with ByteArrayOutputStream

use of java.io.ByteArrayOutputStream in project bazel by bazelbuild.

the class ZipCombinerTest method testRenameAndSkip.

// This tests verifies that if an entry has been skipped, then
// further entries of the same name are skipped (filter not invoked),
// and entries renamed to the same name are skipped (after calling filter).
@Test
public void testRenameAndSkip() throws IOException {
    MockZipEntryFilter mockFilter = new MockZipEntryFilter();

    ByteArrayOutputStream out = new ByteArrayOutputStream();

Example 48 with ByteArrayOutputStream

use of java.io.ByteArrayOutputStream in project bazel by bazelbuild.

the class ZipCombinerTest method testRenameWithUncompressedFiles.

// This test verifies that renaming works when input and output
// disagree on compression method. This is the simple case, where
// content is read and rewritten, and no header repair is needed.
