/**

public class TestCase {
    private String caseId;
    private String describe;
    private String url;
    private String method;
    private String parameters;
    private String expect;
    private String actual;

    public String getCaseId() {
        return caseId;
    }

    public void setCaseId(String caseId) {
        this.caseId = caseId;
    }
