Arrya Code

the title might little confusing want know how can change ' b ' part in mainsave.b define within object. here code far public void getitem(int a, string b) { mainsave.b = a; } the values being sent piece of code in class called story. want them stored in object of class savefile 'mainsave' is if (command_string.equals("1")) { try {thread.sleep(1500);} catch (interruptedexception e) {} system.out.println("you search shed thouroughly , find axe not else..."); int item = 1; string axe = "axe"; getitem(item,axe); try {thread.sleep(1500);} catch (interruptedexception e) {} area1(); } the error when trying compile first part "cannot find symbol - variable b" simply cannot since java statically typed language. variables names must realize @ compile time. i don't suggest possible reflection coding.

i want write unit test checks callout hasn't been made trigger. know how test if callout made correctly - implementing httpcalloutmock: global class myhttpcalloutmock implements httpcalloutmock { global httpresponse respond(httprequest req) { //test httprequest here } } but if no http request made, respond() method won't called. approach doesn't test if request made @ all. need this: httprequest.assertnorequestshavebeenmade(); how do that? so figured out. turns out salesforce has methods test.starttest() , test.stoptest() make asynchronous callouts synchronous: https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_testing_tools_start_stop_test.htm after making callouts synchronous it's easier test them.
