Sm2Test 中拆开执行报错而放在一起执行正确的问题

[rarnu]

https://github.com/GmSSL/GmSSL-Java/blob/main/src/test/java/org/gmssl/Sm2Test.java

具体原因是因为 @BeforeTest 每次都重新生成key

@Before
  public void beforeTest(){
      sm2_key = new Sm2Key();
      sm2_key.generateKey();
  }

需要将key固化到磁盘，然后在其他的测试用例内加载，即可解决问题

class TestSm2 {

    private val sm2Key = Sm2Key(has_private_key = true)

    @Test
    fun generateKeys() {
        sm2Key.generateKey()
        sm2Key.exportPublicKeyInfoPem("publickey.pem")
        sm2Key.exportEncryptedPrivateKeyInfoPem("12345678", "privatekey.pk8")
    }

    private fun loadKeys() {
        sm2Key.importPublicKeyInfoPem("publickey.pem")
        sm2Key.importEncryptedPrivateKeyInfoPem("12345678", "privatekey.pk8")
    }

    @Test
    fun testEncrypt() {
        loadKeys()
        val testStr = "gmssl"
        val ciphertext = sm2Key.encrypt(testStr.toByteArray())
        val textHex = HexUtil.byteToHex(ciphertext)
        println(textHex)
    }

    @Test
    fun testDecrypt() {
        loadKeys()
        val textHex = "306f0221008d769703b894dbf832409e2497f87a52bd203d83e7d56616a95ff8597ee0b5fb022100befc69ee3141f53e94ddfa2155f1bd3289e5c7b6cdc828bd4b7fdd49f4360d0f04206300ec08d80eab55c7999fb5c114da7398d76d575bc20ddf881627497fd14aa404051136b536c6"
        val ciphertext = HexUtil.hexToByte(textHex)
        val plaintext = sm2Key.decrypt(ciphertext)
        val plaintextStr = String(plaintext)
        println(plaintextStr)
    }
}
