java - What are alternatives to JUnit's assertEquals() method in order to see in the test report which fields of objects differed on comparison? -

-

i have lot of automated tests written in java on junit , use assertequals(java.lang.string message, java.lang.object expected, java.lang.object actual). if compare primitive types in case of assert failure visible in test report values different, e.g. in case of 2 integers comparison. when compare 2 complex objects output of test can quite cluttered. if have override tostring() method list fields values output long. imagine having class:

public class invoice {      private localdate invoicedate;     private string invoicenumber;     private invoicetype invoicetype;     private invoicestatus invoicestatus;     private string mediaplanner;     private string yourreference;     private string responsibleperson;     private brand advertiser;     private mediaagency mediaagency;     private set<invoicerow> invoicerows;     .....

the invoicerow quite complex object lot of own fields. if put these fields tostring() implementation , assert fails junit output quite long message not easy read eyes in order see in 1 object invoice type, example, incorrect.

is there tools/approaches improve in way test report show rather clear , concise output in case when comparison fails? maybe should use other test frameworks has more tooling/features?

implement own assert method.

import static org.junit.assert.assertequals; ... public static void assertequals(invoice expected, invoice actual) {     assertequals("invoicedate", expected.invoicedate, actual.invoicedate);     assertequals("netprice", expected.netprice, actual.netprice);     assertequals("invoicerows", expected.invoicerows, actual.invoicerows);     // , on... }

Android volley - avoid multiple requests of the same kind to the server? -

-
i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
