How to write Test Class for below @Remote Action?

@RemoteAction
    public static List<Lawson_Division__c> getData(String sObjVal,String labelField,String valueField,String param){
        param = String.escapeSingleQuotes(param);
        Id usrId = UserInfo.getUserid();
        String buvalues = [select Muni_Business_Unit_ID__c from user where id=:usrId].Muni_Business_Unit_ID__c;
        if(buValues == null){
           return null; 
        }
        if(buValues != null &&  buValues.EqualsignoreCase('All')){
           return Database.query('SELECT '+valueField+','+labelField+',Business_Unit_Number__c,Area__c,Region__c,BU_Description__c FROM '+sObjVal+' WHERE '+labelField+' LIKE \''+param+'%\''); 
        }
        List<String> buIds = buValues.split(',');
        return Database.query('SELECT '+valueField+','+labelField+',Business_Unit_Number__c,Area__c,Region__c,BU_Description__c FROM '+sObjVal+' WHERE '+labelField+' LIKE \''+param+'%\' and business_unit_number__c in :buIds');
    }

Hi,
You can write test class following way. 
@isTest(SeeAllData=true)
private class	TestController
{
	
  private static testmethod void testgetData()
  {
	test.startTest();
	
	String sObjVal='Account';
	String labelField='Name';
	String valueField='Name';
	String param='Test';
	
	// to use SeeAllData=true  not good practice hence you can create test data here as per your need. then call method
	System.assertNotEquals(null,Class_Name.getData(sObjVal,labelField,valueField, param));
	
	test.stopTest();
  }  
}

Please follow below salesforce Best Practice for Test Classes :-

1. Test class must start with @isTest annotation if class class version is more than 25
2. Test environment support @testVisible , @testSetUp as well
3. Unit test is to test particular piece of code working properly or not .
4. Unit test method takes no argument ,commit no data to database ,send no email ,flagged with testMethod keyword .
5. To deploy to production at-least 75% code coverage is required 
6. System.debug statement are not counted as a part of apex code limit.
7. Test method and test classes are not counted as a part of code limit
9. We should not focus on the  percentage of code coverage ,we should make sure that every use case should covered including positive, negative,bulk and single record .
Single Action -To verify that the the single record produces the correct an expected result .
Bulk action -Any apex record trigger ,class or extension must be invoked for 1-200 records .
Positive behavior : Test every expected behavior occurs through every expected permutation , i,e user filled out every correctly data and not go past the limit .
Negative Testcase :-Not to add future date , Not to specify negative amount.
Restricted User :-Test whether a user with restricted access used in your code .10. Test class should be annotated with @isTest .
11 . @isTest annotation with test method  is equivalent to testMethod keyword .
12. Test method should static and no void return type .
13. Test class and method default access is private ,no matter to add access specifier .
14. classes with @isTest annotation can't be a interface or enum .
15. Test method code can't be invoked by non test request .
16. Stating with salesforce API 28.0 test method can not reside inside non test classes .
17. @Testvisible annotation to make visible private methods inside test classes.
18. Test method can not be used to test web-service call out . Please use call out mock .
19. You can't  send email from test method.
20.User, profile, organization, AsyncApexjob, Corntrigger, RecordType, ApexClass, ApexComponent ,ApexPage we can access without (seeAllData=true) .
21. SeeAllData=true will not work for API 23 version eailer .
22. Accessing static resource test records in test class e,g List<Account> accList=Test.loadData(Account,SobjectType,'ResourceName').
23. Create TestFactory class with @isTest annotation to exclude from organization code size limit .
24. @testSetup to create test records once in a method  and use in every test method in the test class .
25. We can run unit test by using Salesforce Standard UI,Force.com IDE ,Console ,API.
26. Maximum number of test classes run per 24 hour of period is  not grater of 500 or 10 multiplication of test classes of your organization.
27. As apex runs in system mode so the permission and record sharing are not taken into account . So we need to use system.runAs to enforce record sharing .
28. System.runAs will not enforce user permission or field level permission .
29. Every test to runAs count against the total number of DML issued in the process .

Try to avoid see all data true.

NOTE:- You can call remote method same like static method.

className.methodName();

Please try below code. I hope that will help you 
@isTest
private class	ControllerTest
{
  private static testmethod void TestMethod()
  {
	test.startTest();

		Lawson_Division__c obj = new Lawson_Division__c();
		obj.Name='test';
		// Please add all required field here 
		insert obj;
	
		String sObjVal='Lawson_Division__c';
		String labelField='Name';
		String valueField='Name';
		String param='Test';
	
	
		System.assertNotEquals(null,Class_Name.getData(sObjVal,labelField,valueField, param));
	
	test.stopTest();
  }  
}

HI Vivek,
Thank you for Helping me.
below is the entire class and the test class which i have modified based on your test class.

Please try below test class. I hope that will help you 
@isTest
public class   TestAutoComplete_Con
{
  public static testmethod void testgetDataTest()
  {
    

		List<Lawson_Division__c> pcList = new List<Lawson_Division__c>();
		for(Integer i =0 ; i < 200 ; i++){
			pcList.add(new Lawson_Division__c(Name='Test'+i));
		}

		insert pcList;

		test.startTest();
			AutoComplete_Con ACP = new AutoComplete_Con();
			
List<Lawson_Division__c> lst= ACP.getData(ACP.sObjVal, ACP.labelField ,ACP.valueField , 'Test1');
		Test.stopTest();
  }  
}

Please let us know if this will help u.

Hi
could anybody please tell me how to write the test class for this.I am new in writing the test classes.
Kindly help.
i tried writing by calling the methods but it tells variable doesnt exist. i think i am wrong somewhere.
help please.
Code snippet below



@RemoteAction
    public static String encryptDecryptUName(String uname, String action) {
        if(action == 'encrypt'){
            Blob cryptoKey = EncodingUtil.base64Decode(key);
            // Generate the data to be encrypted.  
            Blob data = Blob.valueOf(uname);
            // Encrypt the data and have Salesforce.com generate the initialization vector   
            Blob encryptedData = Crypto.encryptWithManagedIV('AES256', cryptoKey, data);
            String dataStr = EncodingUtil.base64Encode(encryptedData);
            return dataStr;
        }
        if(action == 'decrypt'){
            Blob cryptoKey = EncodingUtil.base64Decode(key);
            // Generate the data to be encrypted.  
            Blob data = EncodingUtil.base64Decode(uname);
            // Encrypt the data and have Salesforce.com generate the initialization vector   
            Blob decryptedData = Crypto.decryptWithManagedIV('AES256', cryptoKey, data);
            String dataStr = decryptedData.toString();
            return dataStr;
        }
        return null;
        
    }
