MY BIBLE AND HYMNAL

MY 3 KEY CODING RULES TDD Polymorphism Dependency injection

TESTING TDD BDD Acceptance testing Automated UI testing Load testing Web penetration testing

TDD Bread and butter stuff It’s more than just testing that your code works Better architecture Makes changes easier as it removes uncertainty and fear Speeds up development dramatically Faking allows for isolation of code (SOLID principles) We use Moq framework for Faking (Mocking) The difference between a software professional and a person that writes code

TDD cont. Write your test first Run the test and see it fail Write just enough production code to pass that test Rinse and repeat At RisCura we had over 2500 unit tests Ocellics EDM has over 600 and it’s only a year old

TDD ON THE WEB: CLIENT SIDE The rules are the same Tools for testing Javascript that we use: Mocha - framework Sinon – fakes, or rather spies as they are called in JS Others: Jasmine And Jasmine Spies QUnit

BDD The concept is that of an automated test that solves a Use Case Gherkin and SpecFlow:

ACCEPTANCE TESTING Testlodge:

AUTOMATED TESTING Tools Selenium CodedUI WatiN …and many more Works well for bigger teams with mature software applications where the UI does not change regularly We focus on TDD and keeping the UI layer as thin as possible

LOAD AND PENETRATION TESTING Visual Studio has built in tools for load testing Other tools on the market if you do some googling… Some top web security risks Injection Broken Authentication and Session Management Cross-Site Scripting (XSS) …full course on the rest listed in resources slide Incredibly critical within the finance industry Some of our clients request 3 rd party penetration testing

WHAT DOES OCELLICS DO? We use the latest tech on the Microsoft stack All the groovy stuff like Entity Framework code first, Web API, MVC, Jquery, Angular etc… Unit tests

WHAT DOES OCELLICS DO? Cont. We are focused in the financial industry We build tactical solutions for clients that help with decision making. We spin off products when the opportunity arises. Data storage solutions with data provision Data focused, algorithms, reporting and charting

ADVICE FOR GRADUATES Focus on learning Find a company that has a culture that cultivates learning and knowledge share I have interviewed many people with great salaries but lack real programming experience Be careful of big companies – don’t get stuck doing the same thing for 10 years Golden hand-cuffs Use your free time wisely Work on pet projects Use resources like Pluralsight Know your worth in the market Prove yourself first, it makes negotiation much easier Make yourself indispensable through great, clean and robust code Don’t blackmail a company with poor, buggy and unstable code
