Usage [↑]

Quick example [↑]

import createServer from "@egomobile/http-server";
import { setupTestEventListener } from "@egomobile/http-supertest";

const app = createServer();

// s. https://github.com/egomobile/node-http-server/wiki/Testing
app.controllers();

// register `test` event: https://egomobile.github.io/node-http-server/interfaces/IHttpServer.html#on
setupTestEventListener({
  server: app,
});

await app.test();
Copy

Filters [↑]

If you defined a lot of tests and want to skip some of them, you can use EGO_TEST_FILTER environment variable.

It can hold a non-empty value, that is a Filtrex expression.

If it returns a truthy value, the underlying test will be executed.

Beside shipped-in functions and constants, the module also provides the following enhancements:

Functions:

Signature	Description	Example
all(value, ...subStrings): bool	Checks if all substrings are part of value.	all("foo bar buzz", "bar", "buzz")
any(value, ...subStrings): bool	Checks if at least one substring is part of value.	any("foo bar buzz", "test", "bar")
endsWith(value, suffix): bool	Checks if a string ends with a suffix.	endsWith("Test string", " string")
float(value): number|false	Converts a string to a float.	float("12.3") == 12.3
indexOf(value): number	Returns the zero-based index of a substring inside a string, and -1 if it is not found.	indexOf("666.0", ".") == 3
int(value): number|false	Converts a string to an integer.	int("10.0") == 10
isNaN(value, float = true): bool	Checks if a value cannot be parsed as number.	isNaN("is not a really number")
join(sep, ...values[]): bool	Handles values as strings an join them with a separator.	join("+", "a", "b", " c") == "a+b+ c"
norm(value): string	Normalizes a string for better comparison: creates lower case version, trims it and replace special characters like umlauts or whitespace	norm("  A tesT String: Ä    ö Ü ß ") == "a test string: ae oe ue ss"
log(value [, returnValue = false]): any	Logs a value.	log(methodName) or methodName == "getAllUsers"
lower(value): string	Converts string to lower case chars.	lower("ThIs Is A tEsTsTrInG") == "this is a test string"
regex(value, pattern [, flags = "i"]): bool	Tests a string for a regular expression.	not regex(methodName, "^(ZZZ)(\\s)(-)")
str(value): string	Converts a value to a safe string.	str(1) == "1"
startsWith(value, prefix): bool	Checks if a string starts with a prefix.	startsWith("Test string", "Test ")
trim(value): string	Removes leading and ending whitespace characters from a string.	trim(" Test String ") === "Test String"
trimEnd(value): string	Removes ending whitespace characters from a string.	trimEnd(" Test String ") === " Test String"
trimStart(value): string	Removes leading whitespace characters from a string.	trimStart(" Test String ") === "Test String "
upper(value): string	Converts string to upper case chars.	upper("ThIs Is A tEsTsTrInG") == "THIS IS A TEST STRING"

Constants:

Name: type	Description	Example
context: string	The context in what the test is executed.	context == "controller"
countFailure: number	The current number of failed tests.	countFailure > 0
description: string	The description of the test.	any(description, "foo")
escapedQuery: string	The escaped query string.	a=foo%20bar&b=buzz
escapedRoute: string	The escaped route of the endpoint.	escapedRoute == "/foo%20bar/buzz"
file: string	The full path of the file.	file == "/path/to/endpoints/file/index.ts"
group: string	The name of the current test group, which is usually the name of the controller class.	group == "MyControllerClass
httpMethod: string	Upper case HTTP method.	httpMethod in ("POST", "GET", "PATCH", "DELETE")
methodName: string	The name of the controller method, that is executed by the test.	methodName == "getAllUsers
parameters: string	The JSON string of the object, with all URL parameters.	parameters == "{\"user_id\":\"foo\"}"
query: string	The JSON string of the object, with all query parameters.	query == "{\"a\":\"foo\"}"
route: string	The unescaped route of the endpoint.	route == "/foo bar/buzz"
