 ## Testing signatures
 
 When you finish writing signature, you may want to test the signature.
 rbs provides a feature to test your signature.
 
-```
+```console
 $ RBS_TEST_TARGET='Foo::*' bundle exec ruby -r rbs/test/setup test/foo_test.rb
 ```
 
 The test installs instrumentations to spy the method calls and check if arguments/return values are correct with respect to the type of the method in signature.
 If errors are reported by the test, you will fix the signature.

 ### DuplicatedMethodDefinitionError
 
 The error is reported when a method is defined multiple times, as RBS does not allow duplicate method definitions. When you need to overload a method, use the `...` syntax:
 
-```ruby
+```rbs
 # First definition
 class C
   def foo: () -> untyped
 end

 ### Loading the library
 
 You need to require `rbs/test/setup` for signature testing.
 You can do it using `-r` option through command line argument or the `RUBYOPT` environment variable.
 
-```
+```console
 $ ruby -r rbs/test/setup run_tests.rb
 $ RUBYOPT='-rrbs/test/setup' rake test
 ```
 
 When you are using Bundler, you may need to require `bundler/setup` explicitly.
 
-```
+```console
 $ RUBYOPT='-rbundler/setup -rrbs/test/setup' bundle exec rake test
 ```
 
 ### Environment variables

 `RBS_TEST_OPT` is to pass the options for rbs handling.
 You may need to specify `-r` or `-I` to load signatures.
 The default is `-I sig`.
 
-```
+```shell
 RBS_TEST_OPT='-r pathname -I sig'
 ```
 
 Replacing `pathname` with the `stdlib` you want to include. For example, if you need to load `Set` and `BigDecimal` in `stdlib`, you would need to have `RBS_TEST_OPT='-r set -r bigdecimal -I sig'`

 If the environment variable is set, it raises an exception when a type error is detected.
 You can see the backtrace how the type error is caused and debug your program or signature.
 
 So, a typical command line to start the test would look like the following:
 
-```
+```console
 $ RBS_TEST_LOGLEVEL=error \
   RBS_TEST_TARGET='Kaigi::*' \
   RBS_TEST_SKIP='Kaigi::MonkeyPatch' \

 ### Skipping a method
 
 You can skip installing the instrumentation per-method basis using `rbs:test:skip` annotation.
 
-```
+```rbs
 class String
   %a{rbs:test:skip} def =~: (Regexp) -> Integer?
 end
