For 2023 (and 2024 ...) - we are now fully retired from IT training. We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.
Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!
I am also active in many other area and still look after a lot of web sites - you can find an index ((here)) |
RSpec - Ruby testing (stand alone example / no cucumber)
RSpec can be used as a stand alone test environment for your Ruby program, as well as being used within Gherkin and Cucumber (see [here] for some details of that).
Installation as a Ruby Gem (you may need admin permissions):
gem install rspec
Run your program under the new executable rspec ... on Linux / Unix / OS X start your file with
#!/usr/bin/env rspec
Load the code to be tested - perhaps this class
class StringChanger
def reverse_and_save(string_to_reverse)
string_to_reverse.reverse
end
end
and describe the test
describe StringChanger do
it 'reverses strings' do
string_changer = StringChanger.new
reversed_string = string_changer.reverse_and_save('example from Well House')
expect(reversed_string).to eq 'esuoH lleW morf elpmaxe'
end
end
run it
WomanWithCat:rspec grahamellis$ ./rs001
.
Finished in 0.00073 seconds (files took 0.09143 seconds to load)
1 example, 0 failures
WomanWithCat:rspec grahamellis$
and see that the tests have passed.
