Webunit is a command line client for automated web application tests.

Requirements

PHP >= 8.0

Install with Composer

$ composer require michaelhall/webunit

Basic usage

The webunit client requires a file in text format, containing the tests to run. Pass the name of this file as a command line parameter:

$ webunit testfile

The tests in the test file consists of one or more test cases. Every test case starts with a command. The most basic test case is just a command, e.g.

get https://example.org/

This test will be successful if the Url https://example.org/ is functional and does not return an error or redirect status code. Otherwise, the test will fail.

The Url can also be fetched with one of the other supported HTTP methods:

delete https://example.org/
patch https://example.org/
post https://example.org/
put https://example.org/

A test case can also contain specific assertions:

get https://example.org/
assert-contains Example

Comments and whitespaces can be used to format the test file:

# This is a comment.
get                    https://example.org/
assert-contains        Example

# Another test case.
get                    https://example.org/foobar
assert-status-code     404

Some assertions can be modified with modifier characters:

get                    https://example.org/

# The "!" modifier negates the assertion.
# This assertion will pass if the returned status code is not 404
assert-status-code!    404

# The "^" modifier makes the assertion case insensitive.
# This assertion will pass if result contains "Example", "EXAMPLE", "eXaMpLe" etc.
assert-contains^       example

# The "~" modifier evaluates the assertion as a regular expression.
# This assertion will pass if result contains "Example" or "example".
assert-contains~       [Ee]xample

# Modifiers can be combined.
# This assertion will fail if result contains "FooBar", "foobar" etc.
assert-contains!^      foobar

The request can be modified with request modifiers:

put                    https://example.org/
with-header            Content-Type: application/json
with-raw-content       {"Foo": "Bar"}

The test file can set variables to be reused for the tests.

Variables are evaluated at parse-time in a manner similar to the preprocessor directives in languages like C and C#.

# Set the variable "Url" to the value "https://example.com".
set                    Url = https://example.com/

# get https://example.com/
get                    {{ Url }}

# get https://example.com/another-page
get                    {{ Url }}another-page

It is also possible to set variables from the command line:

$ webunit --set=Url=https://example.com/ testfile

# get https://example.com/
get                    {{ Url }}

A default value can be used to set the variable if not already set.

Example 1:

$ webunit testfile

# "Url" is not set. Set the value to "https://example.com/".
set-default            Url = https://example.com/

# get https://example.com/
get                    {{ Url }}

Example 2:

$ webunit --set=Url=https://example.org/ testfile

# "Url" is already set to "https://example.org/". Do not change it.
set-default            Url = https://example.com/

# get https://https://example.org/
get                    {{ Url }}

The following escape sequences can be used in the test file:

Escape sequence	Character
\n	Line feed
\r	Carriage return
\s	Space
\t	Horizontal tab
\\	Backslash

get                    https://example.org/
assert-contains        <html>\n<head>\n\s
