Question

我得到的是生成AES密钥的几种方法。我在做测试用例，但是当我尝试通过测试验证它返回AES密钥的字符串时，它就失败了。

要调用的方法是：

[ #0 - seda://transform-receive] [CLM] [CID=UNKNOWN] o.a.c.impl.ProcessorEndpoint$1.doStart DEBUG Starting producer: Producer[xslt://./xsl/NI/CGL.xsl?contentCache=false&saxon=true]
[ #0 - seda://transform-receive] [CLM] [CID=UNKNOWN] o.a.camel.impl.ProducerCache  .doGetProducer DEBUG Adding to producer cache with key: Endpoint[xslt://./xsl/NI/CGL.xsl?contentCache=false&saxon=true] for producer: Producer[xslt://./xsl/NI/CGL.xsl?contentCache=false&saxon=true]

和测试:( public String getAESString() { return Base64.encodeToString(this.aesKey.getEncoded(), Base64.DEFAULT); }只调用已经测试的生成AES方法）

setupAES

但是我知道，方法getAesString工作正常，因为我正在使用它测试Activity，我可以使用它，没有问题。

如何避免此错误？（我的意思是，我如何通过考试）

我得到的错误日志是：

@Test
    public void getAESString() throws NoSuchAlgorithmException {
        setupAes();
        assertNotNull(cryptoMancer.getAESString());
    }

图片，显示了该应用程序中完美运行的方法：

当调用String返回的方法时，assertNotNull在AndroidStudio失败
