README

Additional commands to make Codeception local setup easy across teams.

Installation

require the package using Composer:

composer require --dev lucatume/codeception-setup

add the commands to Codeception extensions in the codeception.yml file:

extensions:
    commands:
        - tad\Codeception\Command\SearchReplace
        - tad\Codeception\Command\Setup

Usage

Both the commands will be available on the codecept CLI tool:

codecept search-replace foo bar some-source-file some-destination-file
codecept setup ./setup.yml

Both commands support the --save-config option; when used the value of any option specified to run the command will be written to the commands-config.yaml file.
On subsequent runs any option that has not a value specified for an option will default to the stored one; this is for options (--option-name format) values only, arguments need to be specified every time the command runs.

search-replace

Simply put this command will replace every instance of a string in a file and either rewrite the result in the same file or output the modified content in a specified output file.
Teams sharing files that are used to set up fixtures can automate the "localization" of these fixture files with the command.
An example might be one where a team shares a database dump used to set up acceptance tests in a distribution format; the database dump needs to be customized for each member of the team replacing some values in it.
The below command will replace all instances of http://site.local with http://localhost:8080 in the dump.sql file.

codecept search-replace http://site.local http://localhost:8080 ./tests/_data/dump.sql

To avoid manipulating a common source file an optional output file can be specified like this:

codecept search-replace http://site.local http://localhost:8080 ./tests/_data/dump.dist.sql ./tests/_data/dump.sql

The command is file agnostic and will work on any file; the following is a legit use too:

codecept search-replace http://site.local http://localhost:8080 ./tests/acceptance.suite.dist.yml ./tests/acceptance.suite.yml

If used in a loop some source files might be missing; in that case the --skip-if-missing option can be used to avoid errors when the source file is missing:

FILES="./tests/_data/dump1.sql
./tests/_data/dump2.sql
./tests/_data/dump3.sql"

for f in $FILES
do
    codecept search-replace http://site.local http://localhost:8080 $f --skip-if-missing
done

setup

On the same line of team sharing way more complex set up procedures might be required to set up a local, ready to use and customized testing environment.
While embedding shell scripts in the repository is always an option the setup tries to remove some required knowledge relying on a Yaml configuration file.
If ran without specifying the configuration file to use the command will try to look for a setup.yml file in the project root folder:

codecept setup

The configuration file to use can be specified using the optional argument:

codecept setup local-setup-config.yml

A basic local setup configuration file might be the one below:

foo:
    var:
        name: first
        question: First var value?
        default: 23
    message: Var value is \$first

The console command output will be:

> Configuring "foo"...
> First var value? (23) // user inputs 'bar' and presses Enter
> Var value is bar

if setup instruction

Any instruction can be conditionally executed using the simple if or unless syntax.
An if condition will make sure the instruction is executed if the specified condition is true; an unless condition will make sure the instruction is executed if the specified condition is false.
The condition syntax in both cases is:

<var> (is|not) <value>

The configuration file below will show the message "Hello world" if the "show" variable has not a value of "no".

Show:
    var:
        name: show
        question: Show the message?
        validate: yesno
        default: yes
    message:
        unless: show is no
        value: Hello world

Which is equivalent to:

Show:
    var:
        name: show
        question: Show the message?
        validate: yesno
        default: yes
    message:
        if: show not no
        value: Hello world

Condition can also be an existence one where the chekc is made on a variable being empty or not:

Show:
    var:
        name: show
        question: Show the message?
        validate: yesno
        default: yes
    message:
        if: show
        value: Hello world

for loop setup instruction

The message, command and exec support the for argument.
This argument allows the instruction to be executed an arbitrary number of times looping over a user entered or hard-coded variable.
The setup instructions below will create 3 files in the root folder:

foo:
    exec:
        for: fileName in one,two,three
        value: touch $fileName.txt

the string one,two,three represents an array of comma separated values. The format allows for spaces around commas to improved readability; the setup file below:

foo:
    message:
        for: name in John, Marc, Daniel
        value: Hello $name!

will output:

Hello John! Hello Marc! Hello Daniel!

Variables too can be used in the for loop but those must be integer values:

foo:
    var:
        name: times
        validate: int
        default: 3
        question: How many times to loop?
    message:
        if: times
        for: i in times
        value: Loop run $i

will output, presuming an user input of 4:

Loop run 1 Loop run 2 Loop run 3 Loop run 4

Please note that loops are human-friendly and start at 1 and not 0 as developers are used to.

var

Ask the user for a variable value or store a variable value.
In the first case required fields for the var instructions are:

name - the name the variable will be referenced with across the setup file
question - the question that will prompt the user to enter a value for the variable

If the purpose is to store a value for later use then required fields are:

name - the name the variable will be referenced with across the setup file
value - the value that should be stored in the variable

Optional arguments are:

default - the var default value should the user not provide any value pressing Enter without typing anything
validate - the type the var should be validate with; the command will keep asking for a valid value until the user enters it; supported types are int, float, bool, url, email, yesno.
In addition the regexp validation mode is available supporting default PHP validation.

break

If the setup execution should be stopped then the break instruction can be used.
The instruction has two arguments:

if or unless condition - whether the execution should be stopped or not; required
value - a message to show before the execution is stopped; optional

An example usage:

config-name:
    var:
        name: stop
        question: stop?
        validate: yesno
    break:
        if: stop
        value: Stopped.
    message: Will not see this.

message

Displays a message to the user.
Messages can be one line arguments like this:

config-block:
    message: Hello world!

or multiline arguments to allow specifying a condition:

config-block:
    message:
        if: someVar is yes
        value: Hello world!

In the latter case the value argument is required.
Variable values previously obtained can be replaced in a message using the $varName notation:

config-block:
    var:
        name: yourName
        question: What's your name?
        default: Luca
    message:
        if: yourName
        value: Hello $yourName!

command

Runs a sub-command registered on the the codecept CLI tool; an example might be the search-replace subcommand above.
The command instruction can be a one liner:

config-block:
    command: search-replace foo bar ./tests/_data/dump.dist.sql ./tests/_data/dump.sql

or a multilne instruction if a condition needs to be specified:

config-block:
    var:
        name: runCommand
        validate: yesno
        default: yes
        question: run the command?
    command:
        if: runCommand is yes
        value: search-replace foo bar ./tests/_data/dump.dist.sql ./tests/_data/dump.sql

Variable values previously obtained can be replaced in a command instruction using the $varName notation:

config-block:
    var:
        name: domain
        validate: url
        default: http://local.dev
        question: local development domain?
    command: search-replace http://dist-domain.dev $domain ./tests/_data/dump.dist.sql ./tests/_data/dump.sql

exec

Runs a script using PHP exec() function.
The exec instruction can be a one liner:

config-block:
    exec: touch somefile.txt

or a multilne instruction if a condition needs to be specified:

config-block:
    var:
        name: runExec
        validate: yesno
        default: yes
        question: touch somefile.txt?
    exec:
        if: runExec is yes
        value: touch somefile.txt

Variable values previously obtained can be replaced in an exec instruction using the $varName notation:

config-block:
    var:
        name: fileName
        default: someFile
        question: filename?
    exec: touch $fileName.txt

setup:scaffold

While a setup command consumable file can be easily created the setup:scaffold command was born to give a quick starting point.
Beint project-agnostic it is meant to be used after the local testing environment has been set up.
The command allows for some options:

--destination - by default the command will write a setup file to the setup.yml file in the project root folder: relative paths will be resolved from the project root folder.
--skip-suites - by default the command will generate a distribution version of each suite configuration file (*.suite.yml) if not existing already: use this option to skip it.
--yes - answer y to all confirmation requests the command requires.
