MockMvc: testing  from the server side, simulated servlet dispatcher, but not a container. 


RestTemplate: testing like from client side;

TestRestTemplate:

For my case, the error is due to the response entity data type is not correctly defined; so it confused the json converter. It received an object type A, but it is required to be converted to type B. So it may throw this specific exception.

@Testfun `given right username and password, but not allowed to access this resource, resulting in an authorisation failure`() {
    val response: ResponseEntity = testTemplate.withBasicAuth("testName1", "test1")
            .getForEntity(resource, String::class.java)
    assertThat(response.statusCode, `is`(HttpStatus.FORBIDDEN))
}

@Testfun `given right username and password, but allowed to access the resource, resulting in an ok status`() {
    val response: ResponseEntity

Handling Security Exceptions in Spring Boot

Actually, handling exceptions thrown in the security is different from handling ones thrown from the rest APIs, for they happens in the filters before reaching the Servlet dispatcher.

Hence, we cannot handle security-relevant exceptions in @ControllerAdvice and @ExceptionHanlder,  it needs a different way

Encoding Issue Running Gradle Test

Gradle setup: if having a problem at the command line

It may due to missing encoding set in the Gradle property.

We may setup the encoding convention to force the JVM using a specific encoding strategy.

org.gradle.jvmargs=-Xmx2g -XX:MaxMetaspaceSize=512m 

-XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

Setup Gradle Properties

JVM Configuration Attributes

Intellij setup: if having a problem at the IDE

Intellij  GOTO 'Help' Tab, Click 'Edit Custom VM Option'

adding

-Dfile.encoding=UTF8

Spring Session

HTTP is a stateless protocol, meaning that all requests and responses are independent.

Http session is a way to keep states at a server-side. A cookie is another way to keep states in the client-side.

Spring session is a way to manage a cluster of Http sessions;  across sessions, including their persistence.
