Jmater函數擴展的步驟
1、 導入Jmeter源碼，或使用maven項目，引入依賴的jar包
2、 繼承AbstractFunction，實現自定義Function
3、 繼承JMeterTestCase，對自定義的函數進行單元測試
4、 對自定義函數進行編譯打包，並放在lib\ext下
5、 Jmeter ->選項 ->函數助手對話框，選擇已開發的函數調用
自定義Function
繼上一篇文章已經介紹如何導入Jmeter源碼，這里就不做詳細介紹，此次主要引用自動生成手機號碼為例
import java.util.Collection;
import java.util.LinkedList;
import java.util.List;
import org.apache.jmeter.engine.util.CompoundVariable;
import org.apache.jmeter.samplers.SampleResult;
import org.apache.jmeter.samplers.Sampler;
import org.apache.jmeter.threads.JMeterVariables;
public class MobileGenerator extends AbstractFunction {
private static final List<String> desc = new LinkedList<String>();
//定義function名稱
private static final String KEY = "__MobileGenerator";
private static String[] telFirst = "134,135,136,137,138,139,150,151,152,157,158,159,130,131,132,155,156,133,153"
.split(",");
//自定義function的描述
static {
desc.add("Name of variable in which to store the result (optional)");
}
private CompoundVariable varName;
//執行部分
public String execute(SampleResult previousResult, Sampler currentSampler) throws InvalidVariableException {
int index = getNum(0, telFirst.length - 1);
String first = telFirst[index];
String second = String.valueOf(getNum(1, 888) + 10000).substring(1);
String thrid = String.valueOf(getNum(1, 9100) + 10000).substring(1);
String mobile = first + second + thrid;
if (varName != null) {
JMeterVariables vars = getVariables();
final String varTrim = varName.execute().trim();
if (vars != null && varTrim.length() > 0) {// vars will be null
// on TestPlan
vars.put(varTrim, mobile);
}
}
return mobile;
}
//設置參數值
public void setParameters(Collection<CompoundVariable> parameters) throws InvalidVariableException {
//校驗參數個數 checkParameterCount(Collection<CompoundVariable> parameters, int min, int max)
checkParameterCount(parameters, 0, 1);
//將值存入變量中
Object[] values = parameters.toArray();
if (values.length > 0) {
varName = (CompoundVariable) values[0];
} else {
varName = null;
}
}
@Override
public String getReferenceKey() {
return KEY;
}
@Override
public List<String> getArgumentDesc() {
return desc;
}
private static int getNum(int start, int end) {
return (int) (Math.random() * (end - 1));
}
}
對開發的函數進行單元測試
import static org.apache.jmeter.functions.FunctionTestHelper.makeParams;
import java.util.Collection;
import org.apache.jmeter.engine.util.CompoundVariable;
import org.apache.jmeter.junit.JMeterTestCase;
import org.junit.Test;
public class MobileGeneratorTest extends JMeterTestCase {
@Test
public void test() throws Exception {
MobileGenerator mobileGenerator = new MobileGenerator();
Collection<CompoundVariable> params = makeParams("mobile",null,null);
mobileGenerator.setParameters(params);
String string = mobileGenerator.execute();
System.out.println(string);
}
}
編譯並打包
編譯並打包到lib\ext目錄下，覆蓋下之前的ApacheJMeter_functions.jar，重啟Jmeter
調用自定義函數
