QR Code JIS X 0510 Drawer In Java
Using Barcode creation for Java Control to generate, create QR-Code image in Java applications.
Besides expecting changes, the other common expectation has to do with code that should generate exceptions:
Painting Bar Code In Java
Using Barcode generator for Java Control to generate, create bar code image in Java applications.
describe "#unpublish!" do context "when brand new" do let(:blog_post) { BlogPostcreate :title => 'Hello' } it "raises an exception" do expect { blog_postunpublish! }to raise_exception(NotPublishedError, /not yet published/) end end end
Bar Code Recognizer In Java
Using Barcode decoder for Java Control to read, scan read, scan image in Java applications.
In this example, we attempt to unpublish a brand-new blog post that hasn t been published yet Therefore, we expect an exception to be raised
QR Code JIS X 0510 Printer In C#.NET
Using Barcode creator for Visual Studio .NET Control to generate, create QR-Code image in .NET framework applications.
1828 pending
Quick Response Code Generation In .NET Framework
Using Barcode creator for ASP.NET Control to generate, create QR image in ASP.NET applications.
When you leave the block off of an example, RSpec treats it as pending
QR Code Creation In Visual Studio .NET
Using Barcode maker for Visual Studio .NET Control to generate, create QR image in Visual Studio .NET applications.
describe GeneralController do describe "GET to index" do it "should be implemented eventually" end end
Print QR-Code In VB.NET
Using Barcode drawer for Visual Studio .NET Control to generate, create Quick Response Code image in .NET framework applications.
RSpec
GTIN - 13 Generator In Java
Using Barcode creation for Java Control to generate, create EAN13 image in Java applications.
RSpec prints out pending examples at the end of its run output, which makes it potentially useful for tracking work in progress
Draw Code 39 Extended In Java
Using Barcode generation for Java Control to generate, create Code 3/9 image in Java applications.
Finished in 0096941 seconds 1 example, 0 failures, 1 pending Pending: GeneralController on GET to index should be successful
Drawing UCC.EAN - 128 In Java
Using Barcode creation for Java Control to generate, create GTIN - 128 image in Java applications.
You can also explicitly create pending examples by inserting a call to the pending method anywhere inside of an example
Barcode Generation In Java
Using Barcode encoder for Java Control to generate, create bar code image in Java applications.
describe GeneralController do describe "on GET to index" do it "should be successful" do pending("not implemented yet") end end end
ECC200 Encoder In Java
Using Barcode encoder for Java Control to generate, create Data Matrix 2d barcode image in Java applications.

2 Of 5 Interleaved Creation In Java
Using Barcode drawer for Java Control to generate, create Uniform Symbology Specification ITF image in Java applications.
Interestingly, you can use pending with a block to keep broken code from failing your spec However, if at some point in the future the broken code does execute without an error, the pending block will cause a failure
Data Matrix Printer In VB.NET
Using Barcode creation for .NET framework Control to generate, create Data Matrix 2d barcode image in .NET framework applications.
describe BlogPost do it "defaults to rating of 30" do pending "implementation of new rating algorithm" do BlogPostnewratingshould == 30 end end end
Paint Code128 In C#
Using Barcode creation for .NET Control to generate, create Code 128 image in VS .NET applications.
Pro-tip: You can make all examples in a group pending simply by calling pending once in the group s before block
Make GTIN - 128 In VS .NET
Using Barcode generator for VS .NET Control to generate, create GS1-128 image in Visual Studio .NET applications.
describe 'Veg-O-Matic' do before { pending } it 'slices' do # will not run, instead displays "slices (PENDING: TODO)" end it 'dices' do # will also be pending end it 'juliennes' do # will also be pending end end
Data Matrix 2d Barcode Decoder In .NET Framework

1829 should and should not
Bar Code Creation In .NET Framework
Using Barcode printer for Visual Studio .NET Control to generate, create bar code image in Visual Studio .NET applications.
Rather than xUnit-style assertions, RSpec uses its own funky DSL syntax to do verification, based on a pair of methods called should and should_not RSpec mixes them into the base Ruby Object class at runtime so that they are available on all objects They expect to receive Matcher objects, generated using RSpec expectation syntax
Encoding Data Matrix In .NET
Using Barcode generation for ASP.NET Control to generate, create Data Matrix ECC200 image in ASP.NET applications.
responseshould have_tag('error', 'No matching email addresses found')
Barcode Generation In .NET
Using Barcode maker for ASP.NET Control to generate, create bar code image in ASP.NET applications.
There are several ways to generate expectation matchers and pass them to should (and should_not):
receivershould(matcher) # Passes if matchermatches (receiver) receivershould == expected # any value # the simplest example
182 Basic Syntax and API
# Passes if (receiver == expected) receivershould === expected #any value # Passes if (receiver === expected) receivershould =~ regexp # Passes if (receiver =~ regexp)
Tiger says
This is all fairly dry and academic, but stay with us because we ve got plenty of real-world example in the next few sessions
The process of learning to write expectations is probably one of the meatier parts of the RSpec learning curve One of the most common idioms is should equal, akin to Test::Unit s assert_equal assertion
18210 Implicit Subject
Whether you know it or not, every RSpec example group has a subject Think of it as the thing being described Let s start with an easy example:
describe BlogPost do it { should be_invalid } end
RSpec
By convention, the implicit subject here is a BlogPostnew instance The should call may look like it is being called off of nothing But actually the call is delegated by the example to the implicit subject It s just as if you d written the expression
BlogPostnewshould be_invalid
18211 Explicit Subject
If the implicit subject of the example group doesn t quite do the job for you, you can specify a subject explicitly For example, maybe we need to tweak a couple of the blog post s attributes on instantiation:
describe BlogPost do subject { BlogPostnew :title => 'foo', :body => 'bar' } it { should be_valid } end
Here we have the same delegation story as with implicit subject The should be_valid call is delegated to the subject
