RSpec¶

Usamos RSpec para escribir ejemplos ejecutables del comportamiento esperado de una pequeña parte del código bajo un contexto controlado.

1describe MovieList do
2  context "when first created" do
3    it "should be empty" do
4      movie_list = MovieList.new
5      movie_list.should be_empty
6    end
7  end
8end

Comando rspec¶

$ rspec -h

Usage: rspec [options] [files or directories]

    -I PATH                          Specify PATH to add to $LOAD_PATH (may be used more than once).
    -r, --require PATH               Require a file.
    -O, --options PATH               Specify the path to a custom options file.
        --order TYPE[:SEED]          Run examples by the specified order type.
                                       [default] files are ordered based on the underlying file
                                                 system's order
                                       [rand]    randomize the order of files, groups and examples
                                       [random]  alias for rand
                                       [random:SEED] e.g. --order random:123
        --seed SEED                  Equivalent of --order rand:SEED.
    -d, --debugger                   Enable debugging.
        --fail-fast                  Abort the run on first failure.
        --failure-exit-code CODE     Override the exit code used when there are failing specs.
    -X, --[no-]drb                   Run examples via DRb.
        --drb-port PORT              Port to connect to the DRb server.
        --init                       Initialize your project with RSpec.
        --configure                  Deprecated. Use --init instead.

  **** Output ****

    -f, --format FORMATTER           Choose a formatter.
                                       [p]rogress (default - dots)
                                       [d]ocumentation (group and example names)
                                       [h]tml
                                       [t]extmate
                                       custom formatter class name
    -o, --out FILE                   Write output to a file instead of STDOUT. This option applies
                                       to the previously specified --format, or the default format
                                       if no format is specified.
    -b, --backtrace                  Enable full backtrace.
    -c, --[no-]color, --[no-]colour  Enable color in the output.
    -p, --profile                    Enable profiling of examples and list 10 slowest examples.

  **** Filtering/tags ****

    In addition to the following options for selecting specific files, groups,
    or examples, you can select a single example by appending the line number to
    the filename:

      rspec path/to/a_spec.rb:37

    -P, --pattern PATTERN            Load files matching pattern (default: "spec/**/*_spec.rb").
    -e, --example STRING             Run examples whose full nested names include STRING
    -l, --line_number LINE           Specify line number of an example or group (may be
                                       used more than once).
    -t, --tag TAG[:VALUE]            Run examples with the specified tag, or exclude examples
                                     by adding ~ before the tag.
                                       - e.g. ~slow
                                       - TAG is always converted to a symbol
        --default_path PATH          Set the default path where RSpec looks for examples (can
                                       be a path to a file or a directory).

  **** Utility ****

    -v, --version                    Display the version.
    -h, --help                       You're looking at it.
