Spreewald is a collection of useful steps for cucumber. Feel free to fork.
You can find a list of all contained steps at the end of this README.
Supported versions
Spreewald is currently tested against and Ruby 2.6.6 and 3.0.0 with Rails 7 and Capybara 3.
Installation
Add this line to your application's Gemfile:
gem 'spreewald'
And then execute:
$ bundle install
Require all Spreewald steps by putting
require 'spreewald/all_steps'
into either your support/env.rb
or step_definitions/spreewald_steps.rb
.
Steps are grouped into a number of categories. If you only want to use a subset
of Spreewald's steps, instead of require 'spreewald/all_steps'
, you can pick
and choose single categories by requiring single files like this:
require 'spreewald/email_steps'
require 'spreewald/web_steps'
After that you are good to go and use the steps described below.
Recommended additional setup
We recommend using a features/support/paths.rb
file in your project to define mappings between verbal phrases and your project's routes. You can then use these phrases in steps like Then I should be on ...
or When I go to ...
.
You can find an example in this repository. Please note that you may have to adapt it depending on the namespaces and other setup of your application's routes.
Similarly, you may define a features/support/selectors.rb
file in your project to define mappings of verbal phrases to CSS selectors. You can also find an example for that in this repository. These mappings can be used with steps like Then I should( not)? see (an|the) element for ...
or When I click on the element for ...
.
We also suggest to look at our recommended Capybara defaults as they impact the behavior of many Spreewald steps.
Spreewald binary
Spreewald comes with a binary that prints a list of all Cucumber steps from Spreewald and your project. It will filter the list by any string you pass it. Example usage (e.g. on a linux shell in the root folder of the project which uses Spreewald):
spreewald # lists all steps
spreewald mail # lists all steps that contain "mail"
The binary also prints paths and selectors; run spreewald --help
to learn more.
Waiting for page load
Spreewald's web steps are all aware that you might run them with a Selenium/Capybara webdriver, and wait for the browser to finish loading the page, if necessary.
This is done by rerunning any assertions until they succeed or a timeout is reached.
We consider a couple of potential exceptions as "retriable", including
Capybara::ElementNotFound, (R)Spec::Expectations::ExpectationNotMetError, Capybara::Poltergeist::ClickFailed
You can add your own error class with
ToleranceForSeleniumSyncIssues::RETRY_ERRORS << 'MyCustomError'
You can achieve this in your own steps by wrapping them inside a patiently do
block, like
Then /^I should see "([^\"]*)" in the HTML$/ do |text|
patiently do
page.body.should include(text)
end
end
More info here.
Overriding steps
Thanks to cucumber_priority you can override any step definition from Spreewald with your own pattern. Cucumber will not raise Cucumber::Ambiguous
if your custom steps collide with a Spreewald step.
Recommended Capybara defaults
If you are upgrading from Capybara 2 to Capybara 3, you might see failing tests with Spreewald steps like I should see
. This is caused by a breaking change in Capybara's Finders that accept a :text
option. To activate Capybara 2 behavior globally in your project, enable this flag:
Capybara.default_normalize_ws = true
This will affect all Spreewald steps that are using Capybara's :text
option.
Furthermore, we recommend setting Capybara's matching strategy to :prefer_exact
. This will positively affect Spreewald steps as it prevents the Capybara::Ambiguous
error in the edge case when two fields are matching the given name, but one of the matches includes the name only as a substring.
Capybara.match = :prefer_exact
If you want Spreewald to match fields, links and buttons against the aria-label
attribute, enable the following global configuration in Capybara 2.8+:
Capybara.enable_aria_label = true

Testing
Gemika is used to manage Gemfiles for different ruby versions.
Spreewald has different kind of tests:
- Unit tests live in
spec/
- Test applications for integration tests with various Capybara versions live in
tests/
. - Tests for the Spreewald binary live in
features/
Run all tests for your current ruby version with rake
or rake matrix:tests
. To bundle use rake matrix:install
first.

Steps
browser_tab_steps.rb
-
When I open ... in a new browser tab
Opens the page in a new browser tab and switches to it.
-
When I close the browser tab
Closes the current browser tab and switches back to the first tab.
-
When I switch to the new(ly opened)? browser tab
Waits for the new browser tab to appear, then switches to it.
-
When I switch( back)? to the previous browser tab
Changes the browser context to the second-last browser tab.
-
When I may open a new browser tab
Required for the check whether a new browser tab was opened or not.
-
Then I should( not)? have opened a new browser tab
Example (positive expectation):
When I may open a new browser tab And I click on "Open link in new browser tab" Then I should have opened a new browser tab
Example (negative expectation):
When I may open a new browser tab And I click on "Open link in current browser tab" Then I should not have opened a new browser tab
-
Then there should be (\d+) browser tabs?
-
Then there should be at least (\d+) browser tabs?
development_steps.rb
-
Then it should work...?
Marks scenario as pending, optionally explained with a reason.
-
Then console
Pauses test execution and opens an IRB shell with current context. Does not halt the application- under-test.
-
AfterStep @slow-motion
Waits 2 seconds after each step
-
AfterStep @single-step
Waits for a keypress after each step
email_steps.rb
When specifying the to
, cc
, bcc
, from
or reply_to
targets within email steps, you can either specify email addresses or any arbitrary identifier. When an identifier (other than an email address) is given, Spreewald can try to use this information to determine the associated user and gather its email address automatically over the application's User
model. For this, you may set Spreewald::MailFinder.user_identity
to an attribute name and Spreewald will call User.find_by_<user_identity>(identifier)
and then use the email
of the found user.
For example, if you set reply_to
to the name John Doe
within a scenario step and specify Spreewald::MailFinder.user_identity = 'name'
, Spreewald will call User.find_by_name('John Doe')
, find the according user with this name and expect its email address as reply_to
.
-
When I clear my e?mails
-
Then (an?|no)( HTML| plain-text|) e?mail should have been sent with:
Example:
Then an email should have been sent with: """ From: max.mustermann@example.com Reply-To: mmuster@gmail.com To: john.doe@example.com CC: jane.doe@example.com BCC: johnny.doe@example.com Subject: The subject may contain "quotes" Attachments: image.jpg, attachment.pdf This is the message body. You can use * as a wildcard to omit the rest of a line * Or you can omit multiple lines if the asterisk is the only character in a single line, like this: * """
You may skip lines in the header. Please note: In older versions of Spreewald, unmentioned body lines were skipped. Now you have to use the asterisk explicitly to omit lines in the body.
-
When I follow the (first|second|third)? link in the e?mail
Please note that this step will only follow HTTP and HTTPS links. Other links (such as mailto: or ftp:// links) are ignored.
-
Then no e?mail should have been sent
-
Then I should see "..." in the( HTML| plain-text|) e?mail
Checks that the last sent email includes some text
-
Then show me the e?mail( header)?s
Print all sent emails to STDOUT (optionally only the headers).
-
Then show me the e?mail( header)?s with:
Print a subset of all sent emails to STDOUT This uses the same syntax as
Then an email should have been sent with:
frame_steps.rb
-
When ... inside the ... iframe
You can append
inside the [name or number] iframe
to any other step. Then the step will operate inside the given iframe. Examples:Then I should see "Kiwi" inside the 1st iframe Then I should see "Cherry" inside the fruits iframe When I press "Save" inside the 2nd iframe
-
When I switch to the ... iframe
This step will switch to the iframe identified by its name or number. All further steps will operate inside the iframe. To switch to operating on the main page again, use the step "I switch back to the whole page". Examples:
When I switch to the 1st iframe When I switch to the fruits iframe
Please note: This step is only available for Capybara >= 3.
-
When I switch back to the whole page
This step can be used to switch back to the whole page if you switched to operating inside an iframe before (step
I switch to the ... iframe
).Please note: This step is only available for Capybara >= 3.
session_steps.rb
-
When ... in the browser session "..."
You can append
in the browser session "name"
to any other step to execute the step in a different browser session.You may need to update other steps to allow multiple sessions (e.g. your authentication steps have to support multiple logged in users). More details here.
table_steps.rb
-
Then I should( not)? see a table with (exactly )?the following rows( in any order)?:?
Check the content of tables in your HTML.
See this article for details.
time_steps.rb
Steps to travel through time
This uses Timecop or Active Support 4.1+ to stub Time.now / Time.current. The user is responsible for including one of the two gems.
Please note that the two approaches branch. While ActiveSupport will freeze the time, Timecop will keep it running.
-
When the (date|time) is "?(\d{4}-\d{2}-\d{2}( \d{1,2}:\d{2})?)"?
Example:
Given the date is 2012-02-10 Given the time is 2012-02-10 13:40
-
When the time is "?(\d{1,2}:\d{2})"?
Example:
Given the time is 13:40
-
When it is (\d+|an?|some|a few) (seconds?|minutes?|hours?|days?|weeks?|months?|years?) (later|earlier)
Example:
When it is 10 minutes later When it is a few hours earlier
web_steps.rb
Most of cucumber-rails' original web steps plus a few of our own.
Note that cucumber-rails deprecated all its steps quite a while ago with the following deprecation notice. Decide for yourself whether you want to use them:
This file was generated by Cucumber-Rails and is only here to get you a head start These step definitions are thin wrappers around the Capybara/Webrat API that lets you visit pages, interact with widgets and make assertions about page content.
If you use these step definitions as basis for your features you will quickly end up with features that are:
- Hard to maintain
- Verbose to read
A much better approach is to write your own higher level step definitions, following the advice in the following blog posts:
-
When ... within ...
You can append
within [selector]
to any other web step, even multiple times. Be aware that within will only look at the first element that matches. If this is a problem for you following links, you might want to have a look at the 'When I follow "..." inside any "..."'-step.Example:
Then I should see "some text" within ".page_body"
-
Given I am on ...
-
When I go to ...
-
Then I should be on ...
-
When I press "..."
-
When I follow "..."
-
When I fill in "..." (with|for) "..."
Fill in text field
-
When I fill in "..." (with|for):
Fill in text field with multi-line block You can use a doc string to supply multi-line text
Example:
When I fill in "some field" with: """ Apple Banana Pear """
-
When I fill in "..." (with|for) '...'
Fill in text field
-
When I select "..." from "..."
Select from select box
-
When I check "..."
Check a checkbox
-
When I uncheck "..."
Uncheck a checkbox
-
When I choose "..."
Select a radio button
-
When I attach the file "..." to "..."
Attach a file to a file upload form field
-
Then I should( not)? see "..."
Checks that some text appears on the page
Note that this does not detect if the text might be hidden via CSS
-
Then I should( not)? see /.../
Checks that a regexp appears on the page
Note that this does not detect if the text might be hidden via CSS
-
Then I should( not)? see a field "..."
Checks for the existance of an input field (given its id or label)
-
Then I should( not)? see the (number|amount) ([-\d,.]+)( ...)?
Use this step to test for a number or money amount instead of a simple
Then I should see
Checks for an unexpected minus sign, correct decimal places etc.
See here for details
-
Then I should( not)? see '...'
Like
Then I should see
, but with single instead of double quotes. In case the expected string contains quotes as well. -
Then I should( not)? see "..." in the HTML
Check that the raw HTML contains a string
-
Then I should see an error
Checks that status code is 400..599
-
Then I should( not)? see (an|the) element "..."
Check that an element with the given selector is present on the page.
Example:
Then I should see an element ".panel" Then I should see the element ".panel" Then I should not see an element ".sidebar" Then I should not see the element ".sidebar"
-
Then I should( not)? see (an|the) element for ...
Check that an element with the given selector alias is present on the page.
Example:
Then I should see an element for the panel Then I should see the element for the panel Then I should not see an element for the sidebar Then I should not see the element for the sidebar
-
Then I should see in this order:?
Checks that these strings are rendered in the given order in a single line or in multiple lines
Example:
Then I should see in this order: | Alpha Group | | Augsburg | | Berlin | | Beta Group |
-
Then I should( not)? see a link labeled "..."
Checks that the page contains a link with a given text or title attribute.
-
Then the "..." field should( not)? contain "..."
Checks that an input field contains some value (allowing * as wildcard character)
-
Then the "..." field should( not)? contain:
Checks that a multiline textarea contains some value (allowing * as wildcard character)
-
Then I should see a form with the following values:
Checks that a list of label/value pairs are visible as control inputs.
Example:
Then I should see a form with the following values: | E-mail | foo@bar.com | | Role | Administrator |
-
Then the "..." field should have the error "..."
Checks that an input field was wrapped with a validation error. This is done by checking for different error HTML structures that display errors.
Spreewald first checks for custom error wrappers (if specified), then Boostrap 3 error wrappers (
.form-group.has-error
), then Bootstrap 4/5 error wrappers (:invalid
oris-invalid
) and lastly, Rails error wrappers (field_with_errors
). You are able to specify a custom error wrapper by settingSpreewald.field_error_class = 'my-custom-error-class'
which is then used to look for the error class on the current or any ancestordiv
.The same principle applies for matching the error message. First, it will look for the message text (starting from the input element) with a custom XPath (if specified), then one targeting a sibling element with a
help-block
class for Bootstrap 3 and then one targeting a sibling element with aninvalid-feedback
class for Bootstrap 4/5. Rails errors are checked specifically over the field title as this one contains the error message. You may specify the custom XPath by setting (e.g.)Spreewald.error_message_xpath_selector = 'parent::*/child::*[@class="my-error-message"]'
. -
Then the "..." field should( not)? have an error
-
Then the "..." checkbox should( not)? be checked?
-
Then the radio button "..." should( not)? be (checked|selected)
-
Then I should have the following query string:
Example:
I should have the following query string: | locale | de | | currency_code | EUR |
Succeeds when the URL contains the given
locale
andcurrency_code
params -
Then show me the page
Open the current Capybara page using the
launchy
orcapybara_screenshot
gem -
Then I should get a response with content-type "..."
Checks
Content-Type
HTTP header -
Then I should get a download with filename "..."
Checks
Content-Disposition
HTTP headerAttention: Doesn't work with Selenium, see https://github.com/jnicklas/capybara#gotchas
-
Then "..." should( not)? be selected for "..."
Checks that a certain option is selected for a text field
-
Then nothing should be selected for "..."
-
Then "..." should( not)? be an option for "..."
Checks for the presence of an option in a select
-
Then the window should be titled "..."
-
When I reload the page
-
Then (the tag )?"..." should be visible
Checks that an element is actually present and visible, also considering styles. Within a selenium test, the browser is asked whether the element is really visible In a non-selenium test, we only check for
.hidden
,.invisible
orstyle: display:none
