新代码未显示新代码中的新代码

Question

我试图用Junit Test Case涵盖代码的几行。 涵盖了我在调试测试案例后发现的线，但是在新代码的Sonarqube覆盖范围内，这些行未显示为

覆盖

     @Override
    public StandardMapper createMapper(Services services) {
        val objectMapper = ObjectMapperFactory.createObjectMapper();
        TransformerPool transformerPool = new TransformerPool(getTransformerPoolSize());
        try (RetryingTransporter retryingTransporter = new RetryingTransporter(
                new SoapTransporter(objectMapper,Configuration.class));
                ResponseGeneratorService responseGeneratorService = new ResponseGeneratorService(
                        JAXBContext.newInstance(Response.class));
                ConfigurationReader configurationReader = new ConfigurationReader();
                ParsingTransformer parsingTransformer = new ParsingTransformer(
                        new RequestTransformerService(transformerPool));) {
            return new StandardMapper(configurationReader, parsingTransformer, retryingTransporter,
                    responseGeneratorService);
        } catch (Exception e) {
            log.error(TransformerConstants.TRANSFORM + TransformerConstants.ERROR_101, e);
        }
        return null;
    }


    private int getTransformerPoolSize() {
        try {
            String poolSize = ((Function<String, String>) System::getenv).apply(TransformerConstants.TRANSFORMER_POOL_SIZE);
            return Integer.parseInt(poolSize);
        } catch (NumberFormatException nfe) {
            log.error(TransformerConstants.TRANSFORMER_POOL_INITIALIZATION_ERROR, nfe);
        }
        return TransformerConstants.DEFAULT_TRANSFORMER_POOL_SIZE;
    }

尽管测试案例

    @Test
   public void testCreateMapper_validTransformerPoolSize() throws Exception {

       restoreSystemProperties(() -> {
           withEnvironmentVariable(TransformerConstants.TRANSFORMER_POOL_SIZE, "7").execute(() -> {
               Assert.assertTrue(factory.createMapper(null) instanceof StandardMapper);
           });
       });
   }

。是通过并覆盖GetTransFormerPoolSize（）方法的线路，但是当我在测试用例上方运行并将调试点放置在return integer.parseint（poolSize）上时；调试点出现在那里，但是在Sonarqube代码覆盖新代码中，它没有显示为涵盖的

。

return Integer.parseInt(poolSize);
