json-path-assert
================
A library with [hamcrest-matchers](http://hamcrest.org/JavaHamcrest/) for JsonPath.
# Getting started
This library is available at the Central Maven Repository. Maven users add this to your POM.
```xml
<dependency>
<groupId>com.jayway.jsonpath</groupId>
<artifactId>json-path-assert</artifactId>
<version>2.1.0</version>
</dependency>
```
# Usage
Statically import the library entry point:
import static com.jayway.jsonpath.matchers.JsonPathMatchers.*;
Example usage:
// NOTE: The actual evaluation will depend on the current JsonPath configuration
Configuration.setDefaults(...);
// The json to be examined could be represented as a String...
String json = ...;
// a file...
File json = ...;
// or an already parsed json object...
Object json = Configuration.defaultConfiguration().jsonProvider().parse(content);
// Verify validity of JSON
assertThat(json, isJson());
// Verify existence of JSON path
assertThat(json, hasJsonPath("$.message"));
// Verify evaluation of JSON path
assertThat(json, hasJsonPath("$.message", equalTo("Hi there")));
assertThat(json, hasJsonPath("$.quantity", equalTo(5)));
assertThat(json, hasJsonPath("$.price", equalTo(34.56)));
assertThat(json, hasJsonPath("$.store.book[*].author", hasSize(4)));
assertThat(json, hasJsonPath("$.store.book[*].author", hasItem("Evelyn Waugh")));
// Combine several JSON path evaluations
assertThat(json, isJson(allOf(
withJsonPath("$.store.name", equalTo("Little Shop")),
withJsonPath("$..title", hasSize(4)))));
// Use typed matchers for increased clarity
String json = ...
assertThat(json, isJsonString(withJsonPath("$..author")));
File json = ...
assertThat(json, isJsonFile(withJsonPath("$..author")));
