### Question:
TesseractOCRConfig implements Serializable { public void setTesseractPath(String tesseractPath) { tesseractPath = FilenameUtils.normalize(tesseractPath); if (!tesseractPath.isEmpty() && !tesseractPath.endsWith(File.separator)) tesseractPath += File.separator; this.tesseractPath = tesseractPath; } TesseractOCRConfig();  TesseractOCRConfig(InputStream is); String getTesseractPath(); void setTesseractPath(String tesseractPath); String getTessdataPath(); void setTessdataPath(String tessdataPath); String getLanguage(); void setLanguage(String language); String getPageSegMode(); void setPageSegMode(String pageSegMode); String getPageSeparator(); void setPageSeparator(String pageSeparator); void setTrustedPageSeparator(String pageSeparator); void setPreserveInterwordSpacing(boolean preserveInterwordSpacing); boolean getPreserveInterwordSpacing(); long getMinFileSizeToOcr(); void setMinFileSizeToOcr(long minFileSizeToOcr); long getMaxFileSizeToOcr(); void setMaxFileSizeToOcr(long maxFileSizeToOcr); void setTimeout(int timeout); int getTimeout(); void setOutputType(OUTPUT_TYPE outputType); void setOutputType(String outputType); OUTPUT_TYPE getOutputType(); int isEnableImageProcessing(); void setEnableImageProcessing(int enableImageProcessing); int getDensity(); void setDensity(int density); int getDepth(); void setDepth(int depth); String getColorspace(); void setColorspace(String colorspace); String getFilter(); void setFilter(String filter); int getResize(); void setResize(int resize); String getImageMagickPath(); void setImageMagickPath(String imageMagickPath); boolean getApplyRotation(); void setApplyRotation(boolean applyRotation); Map<String, String> getOtherTesseractConfig(); void addOtherTesseractConfig(String key, String value);  }### Answer:
@Test(expected=IllegalArgumentException.class) public void testPathCheck() { TesseractOCRConfig config = new TesseractOCRConfig(); config.setTesseractPath("blah\u0000deblah"); }
