NoSuchAlgorithmException in SSLContext.getInstance

Question

I am getting NoSuchAlgorithmException in the following code:

 @RunWith(PowerMockRunner.class)
 @PrepareForTest({CloudWatchHelper.class})
 class MyTest {
 ....
 final SSLContext sslcontext = SSLContext.getInstance("TLS");
 ...
 }

Stack trace:

[junit] class configured for SSLContext: sun.security.ssl.SSLContextImpl$TLSContext not a SSLContext
[junit] java.security.NoSuchAlgorithmException: class configured for SSLContext: sun.security.ssl.SSLContextImpl$TLSContext not a SSLContext
[junit]     at sun.security.jca.GetInstance.checkSuperClass(GetInstance.java:260)

[junit]     at sun.security.jca.GetInstance.getInstance(GetInstance.java:164)
[junit]     at javax.net.ssl.SSLContext.getInstance(SSLContext.java:156)

I want to know what is the reason behind NoSuchAlgorithmException .

Answer 1

将以下注释添加到我的测试类中为我解决了这个问题：

@PowerMockIgnore({ "javax.net.ssl.*", "javax.security.*" })

Answer 2

当我使用 powermock 时，抛出此异常，解决方法是在测试头上添加 @PowerMockIgnore({ "javax.net.ssl.*" }) 。

Answer 3

I realized that I got exception because of:

 @RunWith(PowerMockRunner.class)
 @PrepareForTest({CloudWatchHelper.class})
