[Feature] Add softly assertion support

[rkarczmarczyk]

At this moment there is no easy way to collect Json asserts in bundle and evaluate it at the end of tests (to show all errors at one test iteration).

There is a way to create custom softly assert but it's not very convenient. You have to do 3 steps:

1. Create class that extends AbstractAssert

   class JsonAssert extends AbstractAssert<JsonAssert, String> {
   JsonAssert(String actual) {
       super(actual, JsonAssert.class);
   }
   public static JsonAssert assertThat(String actual) {
       return new JsonAssert(actual);
   }
   
   JsonAssert isEqualTo(String expected) {
       assertThatJson(actual).isEqualTo(expected);
       return this;
   }
   }

2. Create proxy to already created class in class that extends JUnitSoftAssertions

   public class CustomJUnitSoftAssertions extends JUnitSoftAssertions {
   public JsonAssert assertThatJson(String actual) {
       return proxy(JsonAssert.class, String.class, actual);
   }
   }

3. Used new softly assert in test

   public class SoftlyTest {
   @Rule
   public final CustomJUnitSoftAssertions softly = new CustomJUnitSoftAssertions();
   @Test
   public void test() {
       String actualJson = "{}";
       String expectedJson = "{}";
       softly.assertThatJson(actualJson).isEqualTo(expectedJson);
   }
   }

Waiting for release of this fix in AssertJ https://github.com/joel-costigliola/assertj-core/pull/1352/files

Looks like the issue listed above has been merged.

[lukas-krecan]

It can not be easily implemented since AssertJ softly proxy does not proxy all our methods like node()

[lukas-krecan]

Maybe the new AssertJ features like SoftAssertionsProvider might be the way

Hello, great library, is there any way to use it with softly assertions?

[lukas-krecan]

Hi, unfortunatelly I do not have capacity to implement it. But if you want to try, I welcome PRs.

Ok, thanks for answer.

@rkarczmarczyk Do you happen to know how to make the workaround for an assertion like this?

            assertThatJson(stringArray1)
                    .when(Option.IGNORING_ARRAY_ORDER)
                    .whenIgnoringPaths("[*].key1", "[*].key2")
                    .isArray()
                    .isEqualTo(stringArray2);

EDIT: I figured this out.
