Your test method Testclear() is failing because, the acc variable that is attempted to be cleared in the clear() method, is already null. Hence, you will either need to initialize the acc variable in your constructor or first call the search() method to initialize the acc variable with a value and then call the clear() method.
Refer the sample test code to do so.
static TestMethod void Testclear(){ List<Quote> quotes = new List<Quote>(); //Create test Quote records to be searched and should be retrieved in the acc param for(Integer quoteCnt = 0; quoteCnt < 200; quoteCnt++){ //Include additional Quote fields quotes.add(new Quote()); } //Set the search string accsearchcontroller Obj = new accsearchcontroller(); Obj.searchstring = '30010012'; Test.startTest(); //Call the search() before clear() to initialize the acc variable with a value Obj.search(); Obj.clear(); Test.stopTest(); //Assert if the retireved search results are cleared out System.assertEquals(0, Obj.acc.size()); }Moreover, the methodname clear, is already a standard Sobject method (https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_methods_system_sobject.htm) and a part of the reserved keywords. It may not be directly affecting your code here, but its always a good idea to refrain from using any reserved keywords as method names.
