Variables globales y de environment

Cuando son guardadas hay que guardarlas con JSON.stringify() y extraerlas con JSON.parse()

Environment

Es una serie de key-value pairs, te permiten customizar los requests usando variables que pueden ser cambiadas facilmente

	//guardar variables
	pm.environment.set("variable_key", "variable_value");
	//recuperar variable
	pm.environment.get("variable_key");

Globals

Las globals son variables que estan accesibles en todos los scopes.

	//colocar global variable
	pm.globals.set("variable_key", "variable_value");
	//sacar variable 
	pm.globals.unset("variable_key");

Otras variables

• pm - Variable PostMan, permite acceder a todo lo relacionado con postman
  • pm.response - Contiene la respuesta del request
    • .to.have.status(200)
  • pm.environment.get(‘nombre del environment’) - obtiene una variable de environment
  • pm.expect(valor).to.equal(valor)

Tests

	pm.response.to.not.be.error; 
	pm.response.to.have.jsonBody(""); 
	pm.response.to.not.have.jsonBody("error"); 
pm.test("response must be valid and have a body", function () {
// assert that the status code is 200
pm.response.to.be.ok; // info, success, redirection, clientError,  serverError, are other variants
// assert that the response has a valid JSON body
pm.response.to.be.withBody;
pm.response.to.be.json; // this assertion also checks if a body  exists, so the above check is not needed
});
pm.expect(pm.response.text()).to.include("string_you_want_to_search");
pm.test("Your test name", function () {
var jsonData = pm.response.json();
pm.expect(jsonData.value).to.eql(100);
});
