- takes_options

Assert that a file's contents contains one or more regexps
- filename
-
The file whose contents to check
- contains
-
either a regexp or array of regexpts that the file's contents must match
Source: show
# File lib/optparse_plus/test/integration_test_assertions.rb, line 8 def assert_file(filename, contains:) contents = File.read(filename) Array(contains).each do |regexp| assert_match(regexp,contents,"Expected #{filename} to contain #{regexp}") end end
Assert that your app has a one-line summary
- stdout
-
The standard out, presumably of running `«your-app» –help`
Source: show
# File lib/optparse_plus/test/integration_test_assertions.rb, line 59 def assert_oneline_summary(stdout) output = stdout.split(/\n/) assert output.size >= 3, "Expected 3 or more lines:\n#{stdout}" assert_match(/^\s*$/,output[1],"Should be a blank line after the banner") assert_match(/^\w+\s+\w+/,output[2],"Should be at least two words describing your app") end
Assert that your app takes the given option(s)
- stdout
-
The standard out, presumably of running `«your-app» –help`
- options
-
options your app should take. Put the literal value in here e.g. `–foo` or `–[no-]bar`. The array form is to
allow you to assert long and short options for readable tests:
assert_option(stdout, "--version")
assert_option(stdout, "-h", "--help")

# File lib/optparse_plus/test/integration_test_assertions.rb, line 51 def assert_option(stdout, *options) options.each do |option| assert_match(/#{Regexp.escape(option)}/,stdout) end end
