postman test example -- assertion

Let's see some examples of postman tests. Most of them are as internal postman snippets. Most tests are as simple as a single-line JavaScript statement. You can have as many tests as you want with one request.

Note: The test script runs after a response has been received from the server.

Test example

1. Set environment variables
postman.setEnvironmentVariable("key", "value");
Example: postman.setEnvironmentVariable("url", "http://192.168.36.47/v2/api");
Use the format of environment variables : {{url}}

1.1 Clear the environment variable
postman.clearEnvironmentVariable("variable_key");
Example: postman.clearEnvironmentVariable("url");

2. Set a global variable
postman.setGlobalVariable("key", "value");
Example : postman.setGlobalVariable("username", "[email protected]");
Use the global variable format: {{variableName}}

2.1 Clear a global variable
postman.clearGlobalVariable("key", "value");

3. Check that the response body contains a string
tests["Body matches string"] = responseBody.has("string_you_want_to_search");
Example: The response body contains the following field "path": "field is read-only",
tests["Body matches string"] = responseBody.has("field is read-only");
tests["Body matches string"] = responseBody.has("path");

4. Convert XML body to JSON object
var jsonObject = xml2Json(responseBody) ;
Example:

5.Check that the response body is equal to a string
tests["Body is correct"] = responseBody === "response_body_string";
Example: The response body contains the following field "path": "field is read-only",
tests[ "Body is correct"] = responseBody === "response_body_string";

6. Check a JSON value

var data = JSON.parse(responseBody);
tests["Your test name"] = data.value === 100;

7. Existence of Content-Type (case-insensitive check)

tests["Content-Type is present"] = postman.getResponseHeader("Content-Type"); //Note: the getResponseHeader() method returns the header value, if it exists.

8. Content-Type exists (size-sensitive write)

tests["Content-Type is present"] = responseHeaders.hasOwnProperty("Content-Type");

9.

tests["Response time is less than 200ms"] = responseTime < 200;

10. Status The code is 200

tests["Status code is 200"] = responseCode.code === 200;
Example: The status code is 404
tests["Status code is 404"] = responseCode.code === 404;

11. The code contains a String

tests["Status code name has string"] = responseCode.name.has("Created");
Example: Status: 201 CREATED
tests[" Status code is 201"] = responseCode.code === 201;
tests["Status code name has string"] = responseCode.name.has("Created");

12. Status code of successful POST request

tests["Successful POST request"] = responseCode.code === 201 || responseCode .code === 202;

13. JSON data using TinyValidator

var schema = {
"items": {
"type": "boolean"
}
};
var data1 = [true, false];
var data2 = [true, 123] ;

console.log(tv4.error);
tests["Valid Data1"] = tv4.validate(data1, schema);
tests["Valid Data2"] = tv4.validate(data2, schema); the
