The following (victim) tests exhibit order-dependent behavior and fail when EncryptorConfigTest.testEncryptionWithoutEncryptorImplementation (the polluter) runs before them, unless intermediate tests clean the shared static state:

• io.cloudslang.fortest.SensitiveValueTest.testEncryptedStringSensitiveValue
• io.cloudslang.fortest.SensitiveValueTest.testEncryptedStringSensitiveValuePreEncrypted
• io.cloudslang.fortest.SensitiveValueTest.testSensitiveValueEncryptDecrypt
• io.cloudslang.lang.entities.bindings.values.ValueFactoryTest.testCreatePyObjectValueFromValueSensitive
  
When EncryptorConfigTest.testEncryptionWithoutEncryptorImplementation runs first it removes the encryption bean from the application context, leaves EncryptionProvider.encryptor in a polluted state, and may leave SlangEntitiesSpringConfig.applicationContext pointing to the wrong context. The victim tests attempt to create SensitiveValue instances which require encryption but they fail because they either use a cached encryptor with the wrong context, the encryption bean cannot be resolved because the application context is misconfigured, or "Application context bean is missing" errors are triggered.

Additionally, DeserializeTest.testDeserializeInput fails unless SensitiveValueTest.testEncryptedStringSensitiveValuePreEncrypted (or another test that properly initializes the state) is run beforehand. This is because the test requires the SlangEntitiesSpringConfig.applicationContext to be set to a context containing a DummyEncryptor bean and the EncryptionProvider.encryptor cache to be cleared or properly initialized.

Order dependent flaky tests can lead to unreliable results from CI and can erode developer trust in the test suite.

I have included the easily reproducible failures below:

After fixing the Application context bean issue, the test still fails because no encryptors are found:
