## Managing hermetic Python

To make sure that TensorFlow's build is reproducible, behaves uniformly across
supported platforms (Linux, Windows, MacOS) and is properly isolated from
specifics of a local system, we rely on hermetic Python (see
[rules_python](https://github.com/bazelbuild/rules_python)) for all build
and test commands executed via Bazel. This means that your system Python
installation will be ignored during the build and Python interpreter itself

        assertTrue(exception instanceof Exception);
        assertTrue(exception instanceof Throwable);
    }

    public void test_stackTrace() {
        // Test that stack trace is properly set

        assertTrue(exception.getStackTrace().length > 0);

        generator = new TestThumbnailGenerator();
        Map<String, Object> docMap = new HashMap<>();
        docMap.put("id", "doc123");

        // in unit tests without full container
        try {
            generator.createTask("/path/to/thumb.jpg", docMap);
        } catch (Exception e) {
            // Expected when FessConfig is not available

    /**

     * @return the short value in little-endian format
     * @throws IOException if an I/O error occurs

    public short readShort() throws IOException {
        align(2);
        return Short.reverseBytes(this.dis.readShort());
    }

    /**
     * Reads a 32-bit integer value with proper alignment and byte order.

        // Given
        byte[] buffer = new byte[64];
        int bufferIndex = 8;

        // Prepare test data in buffer (40 bytes of data)
        // Use SMBUtil to properly encode times in Windows FILETIME format
        SMBUtil.writeTime(TEST_CREATE_TIME, buffer, bufferIndex);
        SMBUtil.writeTime(TEST_LAST_ACCESS_TIME, buffer, bufferIndex + 8);

However, further setup is required to run tests or programs directly on a device.

First make sure you have a valid developer certificate and have setup your device properly
to run apps signed by your developer certificate. Then install the libimobiledevice and
ideviceinstaller tools from https://www.libimobiledevice.org/. Use the HEAD versions from
