Description

Fixed flaky test: com.adobe.cq.wcm.core.components.internal.models.v2.PageImplTest#testPage
The flakiness was due to the nondeterministic order of key-value pairs of the JSONObject returned by expectedReader.read() and outputReader.read(), thereby causing JUnit's assertEquals() method to potentially fail in the testJSONExport() method https://github.com/adobe/aem-core-wcm-components/blob/5f29cc86b17b6db36cc617805295eb951b6504a1/bundles/core/src/test/java/com/adobe/cq/wcm/core/components/internal/models/v2/PageImplTest.java#L137 https://github.com/adobe/aem-core-wcm-components/blob/5f29cc86b17b6db36cc617805295eb951b6504a1/bundles/core/src/test/java/com/adobe/cq/wcm/core/components/Utils.java#L79
This proposed method changes JUnit's assertEquals() to the NON_EXTENSIBLE comparison mode in JSONAssert.assertEquals() that matches all key-value pairs without the strict ordering constraint
