## Summary
Make a full json content assertion using the minimum amount of code using an expected JSON content with the possibility to add custom field validation.
Make your tests light, easy to write, readable and exhaustive.
This tool is based on the very useful [JSONassert](https://github.com/skyscreamer/JSONassert) one and add the embedded validation system to assert unpredicatable values.
## Examples
The actual JSON you want to validate :
```json
{
"field_1": "some value",
"field_2": "3716a0cf-850e-46c3-bd97-ac1f34437c43",
"date": "2011-12-03T10:15:30Z",
"other_fields": [{
"id": "2",
"link": "https://another.url.com/my-base-path/query?param1=true"
}, {
"id": "1",
"link": "https://some.url.com"
}]
}
```
The expected JSON with embedded validation :
```json
{
"field_1": "some value",
"field_2": "{#uuid#}",
"date": "{#date_time_format:iso_instant#}",
"other_fields": [{
"id": "1",
"link": "{#url#}"
}, {
"id": "2",
"link": "{#url_ending:query?param1=true#}"
}]
}
```

## Quick start
### Core module
JCV add a new JSONComparator implementation to make the possibility to use validators inside the expected JSON,
so it requires the [JSONassert](https://github.com/skyscreamer/JSONassert) dependency to work.
#### Dependencies
Maven
```xml
...
org.skyscreamer
jsonassert
1.5.3
test
com.ekino.oss.jcv
jcv-core
1.6.0-SNAPSHOT
test
...
```
Gradle
```groovy
dependencies {
...
testImplementation 'org.skyscreamer:jsonassert:1.5.3'
testImplementation 'com.ekino.oss.jcv:jcv-core:1.6.0-SNAPSHOT'
...
}
```
Note:
Do not forget to add the maven snapshots repository for SNAPSHOT versions :
Maven
```xml
...
maven-snapshots
http://oss.sonatype.org/content/repositories/snapshots
default
false
true
...
```
Gradle
```groovy
repositories {
maven {
url = uri("https://oss.sonatype.org/content/repositories/snapshots/")
}
}
```
### AssertJ module
A JCV module that supports [AssertJ](https://github.com/joel-costigliola/assertj-core).
#### Example
```java
import static com.ekino.oss.jcv.assertion.assertj.JsonCompareAssert.*;
@Test
void testContainsValidator() throws JSONException {
assertThatJson("{\"field_name\": \"hello world!\"}")
.isValidAgainst("{\"field_name\": \"{#contains:llo wor#}\"}");
}
```
#### Dependencies
Maven
```xml
...
org.skyscreamer
jsonassert
1.5.3
test
org.assertj
assertj-core
3.26.3
test
com.ekino.oss.jcv
jcv-assertj
1.6.0-SNAPSHOT
test
...
```
Gradle
```groovy
dependencies {
...
testImplementation 'org.skyscreamer:jsonassert:1.5.3'
testImplementation 'org.assertj:assertj-core:3.26.3'
testImplementation 'com.ekino.oss.jcv:jcv-assertj:1.6.0-SNAPSHOT'
...
}
```
### Hamcrest module
A JCV module that supports [Hamcrest](https://github.com/hamcrest/JavaHamcrest).
#### Example
```java
import static com.ekino.oss.jcv.assertion.hamcrest.JsonMatchers.*;
import static org.hamcrest.MatcherAssert.*;
@Test
void testContainsValidator() throws JSONException {
assertThat(
"{\"field_name\": \"hello world!\"}",
jsonMatcher("{\"field_name\": \"{#contains:llo wor#}\"}")
);
}
```
#### Dependencies
Maven
```xml
...
org.skyscreamer
jsonassert
1.5.3
test
org.hamcrest
hamcrest
3.0
test
com.ekino.oss.jcv
jcv-hamcrest
1.6.0-SNAPSHOT
test
...
```
Gradle
```groovy
dependencies {
...
testImplementation 'org.skyscreamer:jsonassert:1.5.3'
testImplementation 'org.hamcrest:hamcrest:3.0'
testImplementation 'com.ekino.oss.jcv:jcv-hamcrest:1.6.0-SNAPSHOT'
...
}
```
### WireMock module
A JCV module extension for [WireMock](http://wiremock.org/).
#### Example
Register the extension on your WireMock server:
```kotlin
import com.github.tomakehurst.wiremock.WireMockServer
import com.github.tomakehurst.wiremock.core.WireMockConfiguration
import com.ekino.oss.jcv.assertion.wiremock.JcvRequestMatcherExtension
private val wireMockServer by lazy {
WireMockServer(
WireMockConfiguration()
.dynamicPort()
.extensions(JcvRequestMatcherExtension())
)
}
```
Then you can stub via code:
```kotlin
import com.github.tomakehurst.wiremock.client.WireMock.aResponse
import com.github.tomakehurst.wiremock.client.WireMock.post
import com.github.tomakehurst.wiremock.client.WireMock.urlEqualTo
import com.ekino.oss.jcv.assertion.wiremock.JcvRequestMatcherExtension
wireMockServer.stubFor(
post(urlEqualTo("/some_url"))
.andMatching(
JcvRequestMatcherExtension.toRequestMatcher(
json =
"""
{
"some_field": "{#not_empty#}"
}
"""
)
)
.willReturn(
aResponse()
.withHeader("Content-Type", "text/plain")
.withStatus(200)
.withBody("OK")
)
)
```
Or you can stub via mapping file:
```json
{
"request": {
"method": "POST",
"url": "/some_url",
"customMatcher": {
"name": "equalToJcv",
"parameters": {
"json": {
"some_field": "{#not_empty#}"
},
"ignoreArrayOrder": true,
"ignoreExtraElements": false
}
}
},
"response": {
"status": 200,
"body": "OK"
}
}
```
#### Dependencies
Maven
```xml
...
org.skyscreamer
jsonassert
1.5.3
test
org.wiremock
wiremock
3.9.1
test
com.ekino.oss.jcv
jcv-wiremock
1.6.0-SNAPSHOT
test
...
```
Gradle
```groovy
dependencies {
...
testImplementation 'org.skyscreamer:jsonassert:1.5.3'
testImplementation 'org.wiremock:wiremock:3.9.1'
testImplementation 'com.ekino.oss.jcv:jcv-wiremock:1.6.0-SNAPSHOT'
...
}
```
