- 3. TDD on architectural level @mgrzejszczak @jkubrynski
- 4. What is Consumer Driven Contract @mgrzejszczak @jkubrynski ● Server ● Consumer ● Contract
- 5. Consumer Driven Contract benefits @mgrzejszczak @jkubrynski
- 8. How to solve it @mgrzejszczak @jkubrynski ● Consumer’s tests ● Server tests
- 9. Contract definition @mgrzejszczak @jkubrynski ● Contract defines communication ● Your stub is your contract - verify it! ● Expose your stub to your consumers
- 10. Consumer Technology @mgrzejszczak @jkubrynski Wiremock http://wiremock.org testCompile 'com.github.tomakehurst:wiremock:1.53' { "request": { "method": "GET", "url": "/hello" }, "response": { "status": 200, "body": "Hello world!", "headers": { "Content-Type": "text/plain" } } }
- 11. Server Technology @mgrzejszczak @jkubrynski Accurate REST https://github.com/Codearte/accurest buildscript { repositories { mavenCentral() } dependencies { classpath 'io.codearte.accurest:accurest-gradle-plugin:0.5.0' } } apply plugin: 'accurest'
- 12. Server Technology @mgrzejszczak @jkubrynski Accurate REST def shouldMarkClientAsNotFraud() { given: def request = given() .header('Content-Type', 'application/frud+json') .body('{"clientPesel":"12345678901", "loanAmount":123.123}') when: def response = given().spec(request) .put("/fraudcheck") then: response.statusCode == 200 response.header('Content-Type') == 'application/fraud+json' and: def responseBody = parseText(response.body.asString()) responseBody.fraudCheckStatus == "OK" }
