-- A .http Test Runner --
-------------------------

Test your HTTP APIs with standard http syntax

Features:

  • 📝 Write end to end API REST tests in .http files
  • 🔎 Validate Response status, headers and/or body.
  • 🔥 Interpolate javascript with eta template <%= %>
  • 🖊 Write metadata as frontmatter yaml
  • 📦 Reference by name another test to run them in advance
  • ⏱ Set a timeout for each test or globally in milliseconds. After the timeout, the test will fail.
  • 🚨 Stop running tests after the first failure.
  • 🔋 Use env files to load environment variables
  • 😎 Fully featured and colorful display modes. (none, minimal, default and full)
  • 👁 Watch files for changes and rerun tests.
  • 🍯 Standard Response and Request with a automatic getBody()

Install:

deno install --unstable --allow-read --allow-env -f -n tepi https://deno.land/x/tepi/src/cli.ts

Or run remotely width:

deno run --unstable --allow-read --allow-env https://deno.land/x/tepi/src/cli.ts

Usage:

tepi [OPTIONS] [FILES|GLOBS...]

Options:

  • -w --watch Watch files for changes and rerun tests.
  • -t --timeout Set the timeout for each test in milliseconds. After the timeout, the test will fail.
  • -f --fail-fast Stop running tests after the first failure.
  • -d --display Set the display mode. (none, minimal, default and full) * none: display nothing * minimal: display only a minimal summary * default: list results and full error summary * full: display also all HTTP requests and responses * verbose: display also all metadata and not truncate data
  • -h --help output usage information
  • -e --env-file load environment variables from a .env file
  • --no-color output without color

Examples:

tepi

Run all .http in the current directory and folders. (same as tepi ./**/*.http)

tepi test.http ./test2.http

Run test.http and test2.http

tepi **/*.http

Run all .http in the current directory and folders.

tepi rest.http --watch

Run rest.http and rerun when it changes

tepi rest.http --watch "src/**/*.ts"

Run rest.http and rerun when any .ts file in the src folder changes.

tepi rest.http --watch "src/**/*.json" --watch "src/**/*.ts"

You can use multiple --watch flags. Note: You can use globs here too, but use quotes to avoid the shell expanding them.

tepi --timeout 10000

Set the timeout for each test in milliseconds. After the timeout, the test will fail.

tepi --fail-fast

Stop running tests after the first failure.

tepi --display minimal

Set the display mode. (none, minimal, default and full)

tepi --env-file .env --env-file .env.test

Load environment variables from a .env and .env.test

HTTP syntax:

You can use the standard HTTP syntax in your .http files to run a request and response validation. Use the ### to separate the requests. Use frontmatter yaml to set metadata.


# use yaml front matter before the request
---
ref: loginTest
---
POST https://example.com/onlyAdmin
Authorization: Bearer <%= loginTest.body.jwt %>
Content-Type: application/json

{"name": "Garn"}

# write the expected response to validate the actual response
HTTP/1.1 403 Forbidden

###  requests separator
---
name: optional name
timeout: 500 # must respond in less than 500ms
---
GET /?body=hola&status=400
host: https://faker.deno.dev

Interpolation:

It deno 🔥

Uses eta as template engine, see docs: https://deno.land/x/eta

Use <%= %> to interpolate values.

All the std assertion module is available: https://deno.land/std/testing/asserts.ts

Use <% %> to run custom assertions or custom JS. For example:

GET  http://localhost:3000/users

<% assert(response.status === 200) %>

Or:

    <% if (Math.random() > 0.5) { %>
      GET  http://localhost:3000/users/1
    <% } else { %>
      GET  http://localhost:3000/users/2
    <% } %>

Interpolation scope:

In the Interpolation <%= %> or <% %> you have access to any Deno API and the following variables:

request: The Request from the actual block. meta: The metadata from the actual block. and the frontmatter global metadata. response: The standard Response object from the fetch API from the actual request. (only available in the expected response, after the request) body: The extracted body an alias of await response.getBody() (only available in the expected response, after the request)

[name]: the named block already run for example: <%= loginTest.body.jwt %> or <%= loginTest.response.status %>

The Block signature is:

type Block = {
  meta: {
    [key: string]: any,
  },
  request?: Request,
  response?: Response,
  expectedResponse?: Response,
  error?: Error,
  body?: any,
}
