Select Query not searching through test case in solr

I have a gradle project in which I posted an xml file to solr. when searching any keyword through select query(in browser), I get the desired result. But when I do the same thing in my test case, it doesn’t search anything and give back the result as numFound=0 due to which my test case fails.

this is my test case:

import org.apache.solr.SolrTestCaseJ4;
import org.apache.solr.request.SolrQueryRequest;
import org.junit.BeforeClass;
import org.junit.Test;
    public class SolrQueriesTest extends SolrTestCaseJ4 {
    public static void initTestCore() throws Exception {
        SolrTestCaseJ4.initCore("./solrhome/collection1/conf/solrconfig.xml", "./solrhome/collection1/conf/schema.xml", "./solrhome/");
      private static SolrQueryRequest facetRequest(String filter) {
       return req("qt", "/select", "q", filter);
    public void findAll() {

It’s not clear that this problem is Gradle related. What do you get when you run the test in an IDE?
