Overview

Lorikeet is a command line tool and a rust library to run tests for smoke testing and integration testing. Lorikeet currently supports bash commands and simple http requests along with system information (ram, cpu).

Test plans are defined within a yaml file and can be templated using tera. Each step within a test plan can have multiple dependencies (run some steps before others) and can have expectations about the output of each command.

Steps are run in parallel by default, using the number of threads that are available to your system. If a step has dependencies either by require or required_by attributes, then it will wait until those steps are finished.

As an example, here's a test plan to check to see whether reddit is up, and then tries to login if it is:

check_reddit:
  http: https://www.reddit.com
  regex: the front page of the internet

login_to_reddit:
  http:
    url: https://www.reddit.com/api/login/{{user}}
    save_cookies: true
    form:
      user: {{user}}
      passwd: {{pass}}
      api_type: json
  jmespath: length(json.errors)
  matches: 0
  require:
    - check_reddit

( As a side note, we have added jmespath: length(json.errors) & matches: 0 because an invalid login to reddit still returns a status of 200 OK )

And the output of lorikeet:

$ lorikeet -c config.yml test.yml
- name: check_reddit
  pass: true
  output: the front page of the internet
  duration: 1416.591ms

- name: login_to_reddit
  pass: true
  output: 0
  duration: 1089.0276ms

The name comes from the Rainbow Lorikeet, an Australian Bird which is very colourful. Like a canary in a coal mine, lorikeet is meant to provide a way of notifying when things go wrong. Rather than running one test framework (one colour), it is meant to be more full spectrum, hence the choice of a bird with rainbow plumage.

They are also very noisy birds.

Changes in 0.16.0

• Upgraded dependencies to newer versions
• Updated edition to 2024

Changes in 0.15.0

• Add in a new option to run a step on failure:

on_fail_example:
  value: true
  matches: false
  on_fail:
    bash: notify-send "Lorikeet Failed!"

• We now have releases being generated via github actions

Changes in 0.14.0

• Breaking Change: Add in a default timeout (timeout_ms) for http requests to 30000 milliseconds (30 seconds), This default can be changed as per http options below.

Changes in 0.13.1

• Adds slack webhook support. if there are any steps that have errors, this will be sent to a webhook:

lorikeet -s https://hooks.slack.com/services/<your_webhook_here> test

Changes in 0.13.0

• Breaking Change: The run_steps method returns a stream of steps as they complete, rather than waiting for them all to finish
• More Clippy Lints
• Fixed a compilation error on osx

Changes in 0.12.1

• Fixed all clippy issues
• JMESPath strings are no longer quoted
• Added ability to include step output in subsequent requests. You can do this by including ${step_output.<step_name>} where <step_name> is the name of the step to include as output. Currently you will still need to "require" this step

example_output:
  require: another_step
  http:
    url: http://example.com
    body: |
      ${step_output.another_step}

Changes in 0.12.0

• Update to Tokio 1.0
• Updates to all library dependencies

Changes in 0.11.0

• Initial Async Version
• Updates to library dependencies

Changes in 0.10.0

• Upgrade to 2018 crate format
• Fixed terminal painting on Ubuntu 19.10
• A few minor updates to the library version

Changes in 0.9.0

• Upgrade to Reqwest 0.9.x branch, thanks norcali!

• Added multipart support, body, and headers support to the HTTP request type:

To add custom headers, supply a map of header_name: header_value:

Example Header:
  http:
    url: https://example.com
    headers:
      my-custom-header: my-custom-value

Multipart works in the same way as the existing form option, but allows you to also specify files to upload:

Example Multipart:
  http:
    url: https://example.com
    multipart:
      multipart_field: multipart_value
      file_upload:
        file: /path/to/file

You can also just set a generic body via a string:

Example Body:
  http:
    url: https://example.com
    body: |
      This is a generic POST body

Changes in 0.8.0

• The cli app will not panic if there is an issue reading, parsing or running steps, instead it will output a lorikeet step to display what the error is, and still submit it via webhooks, etc..

• Added in initial delay for a step. If you want to wait an arbitrary period of time before running a step, then you can set an initial delay with the delay_ms parameter. This delay is only executed when the step would normally start, so if you have dependent steps, they will run first, then the delay, then the step.

• Added in Retry Policy: If a test fails, you can retry n times by setting the retry_count property. You can also delay retries by setting the retry_delay_ms parameter.

• Both delay_ms and retry_delay_ms are in milliseconds and must be a positive integer value.

• Added initial junit output so you can use lorikeet with jenkins or another CI server that supports junit xml reports. Use -j report.xml to output junit reports.

Changes in 0.7.0

• The main change here was to change the YAML parsing to remove panics, returning a Result<Vec<Step>> which is a breaking change
• A new function get_steps_raw which takes a &str yaml & anything that implements Serialize as a config context. This mainly allows the library to be used without touching the file system for configs or steps. get_steps still can be provided with paths

Installation

Lorikeet is on crates.io, so you can either run:

cargo install lorikeet

Or clone and build this repo:

cargo build --release

Alternatively, you can download prebuilt from the releases page

Usage

Command line usage is given by lorikeet -h:

USAGE:
    lorikeet [FLAGS] [OPTIONS] [test_plan]

FLAGS:
    -h, --help       Prints help information
    -q, --quiet      Don't output results to console
    -V, --version    Prints version information

OPTIONS:
    -c, --config <config>         Configuration File
    -j, --junit <junit>           Output a JUnit XML Report to this file
    -w, --webhook <webhook>...    Webhook submission URL (multiple values allowed)

ARGS:
    <test_plan>    Test Plan [default: test.yml]

Test Plan

The test plan is the main driver for lorikeet and is already quite flexible. See below for examples and test syntax. By default lorikeet will expect a file test.yml in the current directory.

Config Option

Lorikeet uses tera as a template engine so you can include variables within your yaml test plan. Using -c you can provide the context of the test plan as a seperate yaml file. This file can be in any shape, as long as it's valid yaml.

As an example, say you want to check that a number of servers are up and connected. You can have a config like so:

instances:
  - server1
  - server2
  - server3

And then write your test plan:

{% for instance in instances %}

ping_server_{{instance}}:
  bash: ping -c 1 {{instance}} 2>&1 >/dev/null

{% endfor %}

And run it:

$ lorikeet -c config.yml test.yml
- name: ping_server_server1
  pass: true
  duration: 7.859398ms

- name: ping_server_server2
  pass: true
  duration: 7.95139ms

- name: ping_server_server3
  pass: true
  duration: 7.740785ms

Webhook

You can submit your results to a server using a webhook when the test run is finished. This will POST a json object with the submitter::WebHook shape:

{
    "hostname": "example.hostname",
    "has_errors": true,
    "tests": [{
        "name": "Example Webhook",
        "pass": false,
        "output": "Example Output",
        "error": "Example Error",
        "duration": 7.70
    }]
}

Test Plan syntax

The test plan is a yaml file that is divided up into steps:

<step_name>:
  <step_type>: <options>
  (<description>: <value>)
  (<expect_type>: <value>)
  (<filter_type>: <list or value>)
  (<dependence_type>: <list or value>)

Each step has a unique name and a step type. Optionally, there can be an expect type, and a list of dependencies or dependents.

You can also include a description of what the test does alongside a name, so you can provide a more detailed explanation of what the test is doing

Step Types

There are currently 5 step types that can be configured: bash, http, system, step and value

Bash Step type

The bash step type simply runs the bash command to execute shell scripts:

say_hello:
  bash: echo "hello"

Optionally you can specify not to return the output if you're only interested in the return code of the application:

dont_say_hello:
  bash:
    cmd: echo "hello"
    get_output: false

HTTP Step Type

The HTTP step type can execute HTTP commands to web servers using reqwest. Currently this is a very simple step type but does support status codes and storing cookies per domain.

You can specify just the URL:

check_reddit:
  http: https://www.reddit.com
  matches: the front page of the internet

Or provide the following options:

• url: The URL of the request to submit
• method: The HTTP method to use, such as POST, GET, DELETE. Defaults to GET
• headers: Key/Value pairs for any custom headers on your request
• get_output: Return the output of the request. Defaults to true
• save_cookies: Save any set cookies on this domain. Defaults to false
• status: Check the return status is equal to this value. Defaults to 200
• user: Username for Basic Auth
• pass: Password for Basic Auth
• timeout_ms: Timeout in milliseconds for the request, defaults to 30000 (30 seconds). If set to null or ~ it will never timeout.
• form: Key/Value pairs for a form POST submission. If method is set to GET, then this will set the method to POST
• multipart: Multipart request. Key/Value pairs Like the form option but allows file upload as well.
• body: Like the form/multipart options but a raw string instead of form data for JSON uploads
• verify_ssl: Verify SSL on the remote host. Defaults to true. Warning: Disabling SSL verification will cause Lorikeet to trust any host it communicates with, which can expose you to numerous vulnerabilities. You should only use this as a last resort.

As a more elaborate example:

login_to_reddit:
  http:
    url: https://www.reddit.com/api/login/{{user}}
    save_cookies: true
    form:
      user: {{user}}
      passwd: {{pass}}
      api_type: json

For Multipart, you can specify files like so:

Example Multipart:
  http:
    url: https://www.example.com
    multipart:
      multipart_field: multipart_value
      file_upload:
        file: /path/to/file

For a JSON upload you can use the body field:

Example Raw JSON:
  http:
    url: https://www.example.com
    body: |
      { "json_key": "json_value" }

System Step Type

The system step type will return information about the system such as available memory or system load using the sys-info crate.

As an example, to check memory:

check_memory:
  description: Checks to see if the available memory is greater than 1gb
  system: mem_available
  greater_than: 1048000

The system type has a fixed list of values that returns various system info:

• load_avg_1m: The load average over 1 minute
• load_avg_5m: The load average over 5 minutes
• load_avg_15m: The load average over 15 minutes
• mem_available: The amount of available memory
• mem_free: The amount of free memory
• mem_total: The amount of total memory
• disk_free: The amount of free disk space
• disk_total: The total amount of disk space

Using the greater_than or less_than expect types means you can set thresholds for environment resources:

system_load:
  description: Checks the System Load over the last 15 minutes is below 80%
  system: load_avg15m
  less_than: 1.6

'Step' Step Type

If you want to make more assertions on the one step, you can use the 'step' step type. This type simply returns the output of the other step:

say_hello:
  value: hello

test_step:
  step: say_hello
  matches: hello

This will also implicitly require that the step it gets it output from is run first as a dependency so you don't have to worry about the order.

Value Step Type

The value step type will simply return a value, rather than executing anything.

say_hello:
  value: hello

Filter types

You can filter your output either via regex, jmespath, or remove the output completely. Filters can be provided once off, or as a list, so you can chain filters together:

example_step:
  value: some example
  filters:
    - regex: some (.*)

You can also shorthand provide a filter on the step like so:

example_step:
  value: some example
  regex: some

Note: If the filter can't match against a value, it counts as a test error

Regex Filter

Simply filters out the output of the step based upon the matched value.

```yaml say_hello: value: hello world! regex: (.*)
