Greetings, I currently only am able to achieve anywhere between 16-34% coverage with my current apex test class and am trying to determine ways to improve my apex class coverage.


Here is an instance of my apex class itself
 

APEX CLASS
public class ContactLookupControl {

  public Contact contact {get;set;} // new contact to create
  public List<Contact> results{get;set;} // search results
  public string searchString{get;set;} // search keyword

  public ContactLookupControl() {
    contact = new Contact();
    // get the current search string
    searchString = System.currentPageReference().getParameters().get('lksrch');
    runSearch();  
  }

  // performs the keyword search
  public PageReference search() {
    runSearch();
    return null;
  }

  // prepare the query and issue the search command
  private void runSearch() {
    // TODO prepare query string for complex serarches & prevent injections
    results = performSearch(searchString);               
  } 

  // run the search and return the records found. 
  private List<Contact> performSearch(string searchString) {

    String soql = 'select id, name from contact';
    if(searchString != '' && searchString != null)
      soql = soql +  ' where name LIKE \'%' + searchString +'%\'';
    soql = soql + ' limit 25';
    System.debug(soql);
    return database.query(soql); 

  }

  // save the new contact record
  public PageReference saveContact() {
    insert contact;
    // reset the contact
    contact = new Contact();
    return null;
  }

  // used by the visualforce page to send the link to the right dom element
  public string getFormTag() {
    return System.currentPageReference().getParameters().get('frm');
  }

  // used by the visualforce page to send the link to the right dom element for the text box
  public string getTextBox() {
    return System.currentPageReference().getParameters().get('txt');
  }

}


Here's the test class too

TEST CLASS

@isTest 
public class ContactLookupControlTest {
    static testMethod void validateContactLookupControl() {
        Contact c = new Contact();
            c.FirstName = 'Paul';
            c.LastName = 'Reid';
            c.MailingStreet = '205 Hill Street';
            c.MailingCity = 'Los Angeles';
            c.MailingState = 'CA';
            c.MailingPostalCode = '90015';
            c.Email = 'testingout1@aol.com';
            insert c;
    }
}

Are there any additional steps I can pursue to enable it to work accordingly. Let me know and hope it helps.
