phpunitHow to check if a JSON contains a value in PHPUnit?

To check if a JSON contains a value in PHPUnit, you can use the assertJson() method. This method takes two parameters, the first being the actual JSON string and the second being the expected JSON string.

Example code

$actualJson = '{"name":"John","age":30}';
$expectedJson = '{"name":"John"}';

$this->assertJson($actualJson, $expectedJson);

Output example

OK

The assertJson() method will compare the two JSON strings and check if the actual JSON string contains the expected JSON string. If the expected JSON string is found in the actual JSON string, the test will pass.
