The test harness you should use when writing an ACME challenge strategy
for [Greenlock](https://git.coolaj86.com/coolaj86/greenlock-express.js) v2.7+ (and v3).
for [ACME.js](https://git.coolaj86.com/coolaj86/acme-v2.js) and also [Greenlock](https://git.coolaj86.com/coolaj86/greenlock-express.js) v2.7+ (and v3).
All implementations MUST pass these tests, which is a very easy thing to do (just `set()`, `get()`, and `remove()`).
The tests account for single-domain certificates (`example.com`) as well as multiple domain certs (SAN / AltName),
wildcards (`*.example.com`), and valid private / localhost certificates. As someone creating a challenge strategy
that's not something you have to take special consideration for - just pass the tests.
wildcards (`*.example.com`), and valid private / localhost certificates. No worries on your end, just pass the tests. 👌
**Node v6 Support**: Please build community plugins using node v6 / vanillajs to ensure that all acme.js and greenlock.js users are fully supported.

See `example.js` (it works).
## Overview
## Starter Template
Here's what you could start with.
```js
var tester = require('acme-challenge-test');
// The dry-run tests can pass on, literally, 'example.com'
// but the integration tests require that you have control over the domain
var domain = 'example.com';
tester
.test('http-01', domain, {
// Should set a TXT record for dnsHost with dnsAuthorization and ttl || 300
set: function(opts) {
console.log('set opts:', opts);
throw new Error('set not implemented');
},
// Should remove the *one* TXT record for dnsHost with dnsAuthorization
// Should NOT remove otherrecords for dnsHost (wildcard shares dnsHost with
// non-wildcard)
remove: function(opts) {
console.log('remove opts:', opts);
throw new Error('remove not implemented');
},
// Should get the record via the DNS server's API
get: function(opts) {
console.log('get opts:', opts);
throw new Error('get not implemented');
}
})
.then(function() {
console.info('PASS');
});
```
## dns-01 vs http-01
For `type` http-01:
// `altname` is the name of the domain
// `token` is the name of the file ( .well-known/acme-challenge/`token` )
// `keyAuthorization` is the contents of the file
For `type` dns-01:
// `dnsHost` is the domain/subdomain/host
// `dnsAuthorization` is the value of the TXT record
## Detailed Overview
Here's a quick pseudo stub-out of what a test-passing plugin object might look like:
```js
tester.test('http-01', 'example.com', {
set: function (opts) {
var ch = opts.challenge;
// { type: 'http-01' // or 'dns-01'
// , identifier: { type: 'dns', value: 'example.com' }
// , wildcard: false
// , token: 'xxxx'
// , keyAuthorization: 'xxxx.yyyy'
// , dnsHost: '_acme-challenge.example.com'
// , dnsAuthorization: 'zzzz' }
tester
.test('dns-01', 'example.com', {
set: function(opts) {
var ch = opts.challenge;
// { type: 'dns-01' // or 'http-01'
// , identifier: { type: 'dns', value: 'example.com' }
// , wildcard: false
// , token: 'xxxx'
// , keyAuthorization: 'xxxx.yyyy'
// , dnsHost: '_acme-challenge.example.com'
// , dnsAuthorization: 'zzzz' }
return API.set(...);
}
, get: function (query) {
var ch = query.challenge;
// { type: 'http-01' // or 'dns-01', 'tls-alpn-01', etc
// , identifier: { type: 'dns', value: 'example.com' }
// // http-01 only
// , token: 'xxxx'
// , url: '...' // for testing and debugging
// // dns-01 only, for testing / dubgging
// , altname: '...'
// , dnsHost: '...'
// , wildcard: false }
// Note: query.identifier.value is different for http-01 than for dns-01
return YourApi('POST', 'https://example.com/api/dns/txt', {
host: ch.dnsHost,
record: ch.dnsAuthorization
});
},
get: function(query) {
var ch = query.challenge;
// { type: 'dns-01' // or 'http-01', 'tls-alpn-01', etc
// , identifier: { type: 'dns', value: 'example.com' }
// // http-01 only
// , token: 'xxxx'
// , url: '...' // for testing and debugging
// // dns-01 only, for testing / dubgging
// , altname: '...'
// , dnsHost: '...'
// , wildcard: false }
// Note: query.identifier.value is different for http-01 than for dns-01
return API.get(...).then(function (secret) {
// http-01
return { keyAuthorization: secret };
// dns-01
//return { dnsAuthorization: secret };
});
}
, remove: function (opts) {
var ch = opts.challenge;
// same options as in `set()` (which are not the same as `get()`
return YourApi('GET', 'https://example.com/api/dns/txt', {
host: ch.dnsHost
}).then(function(secret) {
// http-01
//return { keyAuthorization: secret };
// dns-01
return { dnsAuthorization: secret };
});
},
remove: function(opts) {
var ch = opts.challenge;
// same options as in `set()` (which are not the same as `get()`
return API.remove(...);
}
}).then(function () {
console.info("PASS");
});
return YourApi('DELETE', 'https://example.com/api/dns/txt/' + ch.dnsHost);
}
})
.then(function() {
console.info('PASS');
});
```
Note: The `API.get()`, `API.set()`, and `API.remove()` is where you do your magic up to upload a file to the correct
Where `YourApi` might look something like this:
```js
var YourApi = function createApi(config) {
var request = require('@root/request');
request = require('util').promisify(request);
return function (method, url, body) {
return request({
method: method,
url: url,
json: body || true,
headers: {
Authorization: 'Bearer ' + config.apiToken
}
}).then(function(resp) {
return resp.body;
});
}
}
```
### Two notes:
Note 1:
The `API.get()`, `API.set()`, and `API.remove()` is where you do your magic up to upload a file to the correct
location on an http serever, set DNS records, or add the appropriate data to the database that handles such things.
Note 2:
* When `altname` is `foo.example.com` the `dnsHost` will be `_acme-challenge.foo.example.com`
* When `altname` is `*.foo.example.com` the `dnsHost` will _still_ be `_acme-challenge.foo.example.com`!!
* When `altname` is `bar.foo.example.com` the `dnsHost` will be `_acme-challenge.bar.foo.example.com`
