使用 pact-jvm - Java
所以我们有我们的 api,它以十进制/浮点值响应几个参数。"body": { "status": "api is up.", "totalTime": 0.005939006805419922 }" 我尝试使用正则表达式匹配,但协议正文生成数据,这与实际 api 返回的小数不匹配。
package pact;

public class PactTest extends ConsumerPactTest {
@Rule
public PactProviderRule mockProvider = new PactProviderRule("test_provider", "localhost", 1234, this);
String v3Path = "/v3";
private DslPart body = new PactDslJsonBody()
.stringType("status", "api is up.")
.decimalType("totalTime", 0.005939006805419922);
protected PactFragment createFragment(PactDslWithProvider builder) {
Map<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json");
PactFragment fragment = builder
.uponReceiving("response")
.path(v3Path)
.method("GET")
.willRespondWith()
.status(200)
.headers(headers)
.body(body)
.toFragment();
return fragment;
}
@Override
protected String providerName() {
return "test_provider";
}
@Override
protected String consumerName() {
return "test_consumer";
}
@Override
protected void runTest(String url) {
Map response;
try {
response = new ConsumerClient(url).getAsMap(v3Path, "");
} catch (Exception e) {
throw new RuntimeException(e);
}
}
}
协议生成:
{
"provider": {
"name": "test_provider"
},
"consumer": {
"name": "test_consumer"
},
"interactions": [
{
"description": "API v3 endpoint response",
"request": {
"method": "GET",
"path": "/v3"
},
"response": {
"status": 200,
"headers": {
"Content-Type": "application/json"
},
"body": {
"status": "api is up.",
"totalTime": 0.005939006805419922
},
"matchingRules": {
"body": {
"$.status": {
"matchers": [
{
"match": "type"
}
]
},
"$.totalTime": {
"matchers": [
{
"match": "decimal"
}
]
}
}
}
}
}
],
"metadata": {
"pact-specification": {
"version": "3.0.0"
},
"pact-jvm": {
"version": "3.5.0-beta.2"
}
}
}
协议与实际响应的差异:
0) Verifying a pact between test_consumer and test_provider - API v3 endpoint response returns a response which has a matching body
$.body.totalTime -> Expected 0.005939006805419922 but received 0.00545501708984375
差异:
@1
"status": "api is up.",
- "totalTime": 0.005939006805419922
+ "totalTime": 0.00545501708984375
}
那么是否可以使用“eachlike”而不是 decimalType 来匹配这些值的模式?当我查看 eachLike 时,它接受一个字符串和一个 int - https://github.com/DiUS/pact-jvm/blob/master/pact-jvm-consumer/src/main/java/au/com/dius /pact/consumer/dsl/PactDslJsonBody.java#L580
