Junit Dynamic Test Cases data reading from file?
问题
我有一个场景，需要使用来自文本文件的载荷来测试 API。文件中的每一行代表一个载荷。如何根据上述场景动态生成测试用例。
我尝试了以下方法，从一个测试调用另一个测试，但我只能看到父测试通过。
import com.jayway.restassured.http.ContentType;
import com.jayway.restassured.response.Response;
import org.junit.Before;
import org.junit.Test;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import static com.jayway.restassured.RestAssured.given;
public class ExampleTest
{
private TestUtil testUtil;
String payload;
@Before
public void init()
{
testUtil = new TestUtil();
}
@Test
public void runAllTests() throws IOException
{
List<String> request = getFileDataLineByLine();
for(String fileRequest:request)
{
payload=fileRequest;
if(null!=payload) {
testExampleTest();
}
}
}
@Test
public void testExampleTest()
{
String uri = "http://localhost:8080/url";
Response response = given()
.contentType(ContentType.JSON)
.body(payload)
.post(uri)
.then()
.statusCode(200)
.extract()
.response();
}
private List<String> getFileDataLineByLine() throws IOException
{
File file = testUtil.getFileFromResources();
if (file == null)
return null;
String line;
List<String> stringList = new ArrayList<>();
try (FileReader reader = new FileReader(file);
BufferedReader br = new BufferedReader(reader))
{
while ((line = br.readLine()) != null)
{
stringList.add(line);
System.out.println(line);
}
}
return stringList;
}
}
文件读取类:
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.net.URL;
public class TestUtil
{
public File getFileFromResources()throws IOException
{
TestUtil testUtil = new TestUtil();
File file = testUtil.getFileFromResources("testdata.txt");
return file;
}
// get file from classpath, resources folder
private File getFileFromResources(String fileName)
{
ClassLoader classLoader = getClass().getClassLoader();
URL resource = classLoader.getResource(fileName);
if (resource == null) {
throw new IllegalArgumentException("file is not found!");
} else {
return new File(resource.getFile());
}
}
}
如何通过从文件中获取输入来动态生成测试用例呢？
英文:
I have a scenario where to test the api using the payload coming from text file.Each line in file represents one payload.How can I dynamically generate test cases based on the above scenario.
I tried as below calling one test from other ,but i can only see paraent test passed.
import com.jayway.restassured.http.ContentType;
import com.jayway.restassured.response.Response;
import org.junit.Before;
import org.junit.Test;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import static com.jayway.restassured.RestAssured.given;
public class ExampleTest
{
private TestUtil testUtil;
String payload;
@Before
public void init()
{
testUtil = new TestUtil();
}
@Test
public void runAllTests() throws IOException
{
List<String> request = getFileDataLineByLine();
for(String fileRequest:request)
{
payload=fileRequest;
if(null!=payload) {
testExampleTest();
}
}
}
@Test
public void testExampleTest()
{
String uri = "http://localhost:8080/url";
Response response = given()
.contentType(ContentType.JSON)
.body(payload)
.post(uri)
.then()
.statusCode(200)
.extract()
.response();
}
private List<String> getFileDataLineByLine() throws IOException {
File file = testUtil.getFileFromResources();
if (file == null)
return null;
String line;
List<String> stringList = new ArrayList<>();
try (FileReader reader = new FileReader(file);
BufferedReader br = new BufferedReader(reader))
{
while ((line = br.readLine()) != null)
{
stringList.add(line);
System.out.println(line);
}
}
return stringList;
}
File Reading Class:
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.net.URL;
public class TestUtil
{
public File getFileFromResources()throws IOException
{
TestUtil testUtil = new TestUtil();
File file = testUtil.getFileFromResources("testdata.txt");
return file;
}
// get file from classpath, resources folder
private File getFileFromResources(String fileName) {
ClassLoader classLoader = getClass().getClassLoader();
URL resource = classLoader.getResource(fileName);
if (resource == null) {
throw new IllegalArgumentException("file is not found!");
} else {
return new File(resource.getFile());
}
}
}
How can i generate test cases dynamically by taking input from file?

如果您可以将您的文件转换，JUnitParams支持从CSV加载数据。
使用上面链接中存储库的示例：
public class PersonTest {
@Test
@FileParameters("src/test/resources/test.csv")
public void loadParamsFromCsv(int age, String name) {
assertFalse(age > 120);
}
}
英文:
If you can convert your file JUnitParams supports loading data from a CSV.
Using an example from the above link's repository:
public class PersonTest {
@Test
@FileParameters("src/test/resources/test.csv")
public void loadParamsFromCsv(int age, String name) {
assertFalse(age > 120);
}
}
