Skip multiple examples in RSpec? - ruby

Does anyone know a way to skip multiple examples within a group, without duplicating the skip statement between them?
For example, given this test:
describe 'some feature' do
it 'should do something' do
...
end
it 'should do something else too' do
...
end
end
a skip doesn't work if placed before the first example, like so:
describe 'some feature' do
skip 'I would like to skip both with one statement'
it 'should do something' do
...
end
it 'should do something else too' do
...
end
end
An ideal solution would allow me to skip at any level of the example structure (describe/feature, context, and scenario/it) and would skip all children of that level of the hierarchy.
In other words, would allow me to do:
describe 'some feature' do
it 'should do something' do
...
end
it 'should do something else too' do
skip 'just one of these for now'
...
end
end
AND
describe 'some feature' do
skip 'everything within this describe block'
it 'should do something' do
...
end
it 'should do something else too' do
...
end
end
AS WELL AS
describe 'some feature' do
context 'such and such' do
skip 'just this context'
it 'should do something' do
...
end
it 'should do something else too' do
...
end
it 'but do not skip this one' do
...
end
end

As described in the documentation, you can use metadata to skip a context.
describe 'some feature', :skip do
it 'should do something' do
# This example is skipped
end
it 'should do something else too' do
# This example is skipped as well
end
end

Run after block after specific test in Rspec

Is there a way I can run the after/before block after/before a specific test using labels?
I have 3 it blocks
describe "describe" do
it "test1" do
end
it "test2" do
end
after(<<what goes here??>>) do
end
end
How do I run the after block only after test2? Is that possible?
You should use contexts to do this. Something like:
describe "describe" do
context 'logged in' do
before(:each) do
# thing that happens in logged in context
end
after(:each) do
# thing that happens in logged in context
end
it "test1" do
end
end
context 'not logged in' do
# No before/after hooks here. Just beautiful test isolation
it "test2" do
end
end
end
Having if/else conditions in before/after blocks is a code smell. Don't do it that way. It'll only make your tests brittle, error prone, and hard to change.
The best way to do this is just use a context. For your example:
describe "AutomateFr33k's fr33ky tests" do
it "runs test1" do
expect(true).to be_true
end
context "do something afterwards" do
after { puts "running something after test2!" }
it "runs test2" do
expect(5).not_to eq(4)
end
end
end
Yes you can do that, have a look here
You can achieve that using metadata in rspec
RSpec.configure do |config|
config.treat_symbols_as_metadata_keys_with_true_values = true
end
describe "Skip hook demo" do
# If prior to RSpec 2.99.0.beta1
after do
puts "before hook" unless example.metadata[:skip]
end
# If RSpec 2.99.0.beta1 or later
after do |example|
puts "before hook" unless example.metadata[:skip]
end
it "will use before hook" do
end
it "will not use before hook", :skip do
end
end

RSpec before blocks not being called before contexts or describes

Given the following code:
RSpec.configure do |config|
config.before(:all) { puts 'before all' }
config.before(:suite) { puts 'before suite'}
config.before(:context) { puts 'before context'}
config.before(:each) { puts 'before each'}
end
RSpec.describe "SomeClass" do
it 'matches some regex' do
puts 'in first it block'
expect('some string').to match(/.*/)
end
describe 'some group of tests' do
puts 'in some group'
context 'when some thing happens' do
puts 'in context'
it 'does something' do
expect(true).to be_truthy
end
end
end
end
I would expect the following output:
before suite
before all
before context
before each
in some group
in context
in first it block
.before each
But instead I get:
in some group
in context
before suite
before all
before context
before each
in first it block
.before each
Meaning that context or describe gets run before any before configuration I've set up.
I expect it to be the first output because of what I've read here and here.
What do I do when I absolutely need code to run before absolutely anything else in the test files? Including (nested) context or describes? And why doesn't it work the way I expect?
Note: I see the same behavior when I include the before :something statements within the scope of the uppermost describe.
(This question is similar to this question, but not the same. I would like to know why my tests are running this way and what the proper RSpec convention is to run a piece of code before absolutely anything else.)
Version info:
RSpec 3.6
- rspec-core 3.6.0

- rspec-support 3.6.0
UPDATE:
It may be helpful to know some context: I'm writing selenium front end automated tests using the selenium-webdriver gem. Before any and all it blocks run, I need to call a function called navigate() (in order to take me to the web page I'm writing the tests for, this function takes about 30 seconds to run because it takes me through two login pages before it gets to where it needs to go) to be called and complete before anything else happens. In my RSpec file I'm using before blocks in an attempt to make this happen, however rspec keeps running tests before the before blocks, and failing.
If you were to put puts "in some group" and puts "in context" into before(:all) blocks, then the output is closer to what you're expecting.
RSpec.configure do |config|
config.before(:all) { puts 'before all' }
config.before(:suite) { puts 'before suite'}
config.before(:context) { puts 'before context'}
config.before(:each) { puts 'before each'}
end
RSpec.describe "SomeClass" do
it 'matches some regex' do
puts 'in first it block'
expect('some string').to match(/.*/)
end
describe 'some group of tests' do
before(:all) { puts 'in some group' }
context 'when some thing happens' do
before(:all) { puts 'in context' }
it 'does something' do
expect(true).to be_truthy
end
end
end
end
outputs
before suite
before all
before context
before each
in first it block
.in some group
in context
before each
.
or, if you did before(:each) you would get
before suite
before all
before context
before each
in first it block
.before each
in some group
in context
.
The reason for the current output is your puts statements for "in some group" and "in context" are being executed when the file is being parsed, not waiting for RSpec at all. If we gave a different example, without Rspec in the mix, imagine we had a file with just
class SomeClass
puts "in class"
def do_something
puts "doing something"
end
end
if we load that file into an irb session or run it on the command line with ruby, we would see "in class" output in the console even though we haven't done anything with that class.

How to ignore or skip a test method using RSpec?

please guide how to disable one of the below test methods using RSpec. I am using Selenuim WebDriver + RSpec combinations to run tests.
require 'rspec'
require 'selenium-webdriver'
describe 'Automation System' do
before(:each) do
###
end
after(:each) do
#driver.quit
end
it 'Test01' do
#positive test case
end
it 'Test02' do
#negative test case
end
end
You can use pending() or change it to xit or wrap assert in pending block for wait implementation:
describe 'Automation System' do
# some code here
it 'Test01' do
pending("is implemented but waiting")
end
it 'Test02' do
# or without message
pending
end
pending do
"string".reverse.should == "gnirts"
end
xit 'Test03' do
true.should be(true)
end
end
Another way to skip tests:
# feature test
scenario 'having js driver enabled', skip: true do
expect(page).to have_content 'a very slow test'
end
# controller spec
it 'renders a view very slow', skip: true do
expect(response).to be_very_slow
end
source: rspec 3.4 documentation
Here is an alternate solution to ignore (skip) the above test method (say, Test01) from sample script.
describe 'Automation System' do
# some code here
it 'Test01' do
skip "is skipped" do
###CODE###
end
end
it 'Test02' do
###CODE###
end
end
Pending and skip are nice but I've always used this for larger describe/context blocks that I needed to ignore/skip.
describe Foo do
describe '#bar' do
it 'should do something' do
...
end
it 'should do something else' do
...
end
end
end if false
There are a number of alternatives for this. Mainly marking it as pending or skipped and there is a subtle difference between them. From the docs
An example can either be marked as skipped, in which is it not executed, or pending in which it is executed but failure will not cause a failure of the entire suite.
Refer the docs here:
https://relishapp.com/rspec/rspec-core/v/3-4/docs/pending-and-skipped-examples/pending-examples
https://relishapp.com/rspec/rspec-core/v/3-4/docs/pending-and-skipped-examples/skip-examples
There are two ways to skip a specific block of code from being running while testing.
Example : Using xit in place of it.
it "redirects to the index page on success" do
visit "/events"
end
Change the above block of code to below.
xit "redirects to the index page on success" do #Adding x before it will skip this test.
visit "/event"
end
Second way: By calling pending inside the block.
Example:
it "should redirects to the index page on success" do
pending #this will be skipped
visit "/events"
end

Rspec and prevent tests from being run under some circumstances

I use rspec like this:
describe
it 'should check if the xx':
end
How do I prevent some tests in the it end body from being run if some condition is met? For example, if the function is_disabled returns true then the following tests should not run:
it 'should check if the xx1':
end
it 'should check if the xx2':
end
but the following should:
it 'should check if the xx3':
end
it 'should check if the xx4':
end
can you do :
context "if api calls enabled for MC, #app.is_disabled => 'USD' do
it 'should check if the xx3':
end
it 'should check if the xx4':
end
end
Yes, you can use rspec implicit filters. Example:
describe "if the app is enabled", :unless => #app.is_disabled do
it 'should check if the xx3':
end
it 'should check if the xx4':
end
end
describe "if the app is disabled", :if => #app.is_disabled do
it 'should check if the xx1':
end
it 'should check if the xx2':
end
end

Include Rspec examples with variable

I have a few sets of rspecs that all include some shared examples. I would like those shared examples to then include other shared examples, if the original spec had some variable set. Basically this is what I'm trying to do.
Example:
File: spec/test_spec.rb
describe 'some thing' do
let(:some_feature) { true }
describe 'some tests' do
include_examples "shared_tests"
end
end
File spec/shared/shared_tests.rb
shared_examples_for "shared_tests" do
include_examples "feature_specific_tests" if some_feature
end
As expected, this is throwing an error like this:
undefined local variable or method `some_feature`
Is there a way to do this? I thought perhaps I could define #some_feature in a before(:all) block and then use if #some_feature in the shared_examples, but that is always nil.
Rewriting the answer to make it a little clearer:
You had this:
File: spec/test_spec.rb
describe 'some thing' do
let(:some_feature) { true }
describe 'some tests' do
include_examples "shared_tests"
end
end
File spec/shared/shared_tests.rb
shared_examples_for "shared_tests" do
include_examples "feature_specific_tests" if some_feature
end
Change it to:
File: spec/test_spec.rb
describe 'some thing' do
describe 'some tests' do
include_examples "shared_tests" do
let(:some_feature) { true }
end
end
end
File spec/shared/shared_tests.rb
shared_examples "shared_tests" do
if some_feature
it_should_behave_like "feature_specific_tests"
end
# rest of your tests for shared example group
# 'a logged in registered user goes here
end
And it'll all work nicely :-)
