```
public static final String USE_NUMERIC_POINTS_SYSPROP
```
  The name of a sysprop that can be set by users when running tests to force the types of numerics used for test classes that do not have the SolrTestCaseJ4.SuppressPointFields annotation:
  - If unset, then a random variable will be used to decide the type of numerics.
  - If set to true then Points based numerics will be used.
  - If set to false (or any other string) then Trie based numerics will be used.
  See Also:
  
  NUMERIC_POINTS_SYSPROP, Constant Field Values
- NUMERIC_POINTS_SYSPROP
```
public static final String NUMERIC_POINTS_SYSPROP
```
  The name of a sysprop that will either true or false indicating if numeric points fields are currently in use, depending on the user specified value of USE_NUMERIC_POINTS_SYSPROP and/or the SolrTestCaseJ4.SuppressPointFields annotation and/or randomization. Tests can use Boolean.getBoolean(NUMERIC_POINTS_SYSPROP).

  randomizeNumericTypesProperties(), Constant Field Values
- NUMERIC_DOCVALUES_SYSPROP
```
public static final String NUMERIC_DOCVALUES_SYSPROP
```
  The name of a sysprop that will be either true or false indicating if docValues should be used on a numeric field. This property string should be used in the docValues attribute of (most) numeric fieldTypes in schemas, and by default will be randomized by this class in a @BeforeClass. Subclasses that need to force specific behavior can use System.setProperty(NUMERIC_DOCVALUES_SYSPROP,"true") to override the default randomization.

assertJQ
```
public static String assertJQ(org.apache.solr.request.SolrQueryRequest req,

```
Validates a query matches some JSON test expressions and closes the query. The text expression is of the form path:JSON. The Noggit JSON parser used accepts single quoted strings and bare strings to allow easy embedding in Java Strings.
Please use this with care: this makes it easy to match complete structures, but doing so can result in fragile tests if you are matching more than what you want to test.

Parameters:

req - Solr request to execute

delta - tolerance allowed in comparing float/double values

tests - JSON path expression + '==' + expected value

Returns:

The request response as a JSON String if all test patterns pass

Throws:

Exception

getCloudHttp2SolrClient
```
public static org.apache.solr.client.solrj.impl.CloudHttp2SolrClient getCloudHttp2SolrClient(MiniSolrCloudCluster cluster)
