TEPI
– HTTP Test Runner–
Tepi is a test runner for .http files.
Write your tests in .http files and run them with tepi
.
$ cat test.http
GET http://localhost:3000 # fetch a GET Request
HTTP/1.1 200 OK # assert a 200 OK response
Content-Type: text/plain # assert a text/plain content type header
Hola mundo! # assert a body with the text "Hola mundo!"
$ tepi test.http
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 --reload --unstable --allow-read --allow-env --allow-net --allow-run -f -n tepi https://tepi.deno.dev/src/cli.ts
Or run remotely with:
deno run --unstable --allow-read --allow-env --allow-net --allow-run https://tepi.deno.dev/src/cli.ts
Usage:
tepi [OPTIONS] [FILES|GLOBS…]
Options:
- -w
--watch
Watch files for changes and rerun tests. --watch-no-clear
same but without clearing the screen.- -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--no-animation
output without terminal animations--upgrade
upgrade to the latest version
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.
For example, validate the headers, status code, status text and body:
GET https://faker.deno.dev/?body=hola&status=400
HTTP/1.1 400 Bad Request
content-type: text/plain; charset=utf-8
hola
Interpolation:
It’s 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) - [id]: the id of a block already run for example:
<%= login.body.jwt %>
or<%= login.response.status %>
The Block signature is:
type Block = {
meta: {
[key: string]: any,
},
request?: Request,
response?: Response,
expectedResponse?: Response,
error?: Error,
body?: any,
}
The request, response and expectedResponse has a custom method async getBody()
to extract the body as json, text or blob depending on the content-type.
The body
is an alias for await response.getBody()
.
For example:
---
id: hello
---
GET https://faker.deno.dev/?body=hola
HTTP/1.1 200
hola
###
POST https://faker.deno.dev/
<%= hello.body %>
HTTP/1.1 200 OK
hola
Special metadata keys:
There are some especial metadata keys used by tepi, as: meta.needs, meta.id, meta.description, meta.display, meta.timeout and meta.import
meta.delay:
The meta.delay allows you to delay the execution of the request fetch for a specific time in milliseconds.
meta.timeout:
The meta.timeout allows you to override the global timeout for a specific test. If the request takes longer than the timeout, the test will fail. The delay is not included in the timeout.
meta.needs
The meta.needs is a special metadata value that allows you to run a test in advance and use the result in the current test if needed.
For example:
---
needs: login
# will run the login test before this one
---
GET https://example.com/onlyAdmin
Authorization: Bearer <%= login.body.jwt %>
Content-Type: application/json
###
---
id: login
---
POST https://example.com/login
Content-Type: application/json
{"user": "Garn", "password": "1234"}
HTTP/1.1 200 OK
meta.id and meta.description
The meta.id allows you to identify a test for reference. The meta.description it’s used to display the test name in the console if not set, it will use the meta.id.
meta.import:
The meta.import allows you to import a file before running the test. The imported file will run before the file that imports it.
meta.display:
The meta.display allows you to override the global display mode for a specific test.
For example:
---
display: verbose
---
GET https://example.com/get
