Developer Tester Collaboration: The Practical Side

Updated with new organization and a bit of new content from my talk at QA Or The Highway in Feb, 2015.

Yes, Developers and Testers should spend more time talking. Yes, each can learn from the other. Your projects will go much more smoothly, and you'll deliver better software to your customers.

This deck is from my talk at SQADays 14 in Lviv, Ukraine.

45. [Test] public void one_method_to_rule_them_all() { var profile = new FirefoxProfile(); var exe = new FirefoxBinary(@"D:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe"); IWebDriver browser = new FirefoxDriver(exe, profile); WebDriverWait w = new WebDriverWait(browser,TimeSpan.FromSeconds(10)); browser.Navigate().GoToUrl("http://localhost/AJAXDemos/CascadingDropDown/CascadingDropDown.aspx"); //browser.Navigate().GoToUrl("http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/CascadingDropDown/CascadingDropDown.aspx"); w.Until(ExpectedConditions.ElementExists(By.XPath("id('ctl00_SampleContent_DropDownList1')/option[text()='Acura']"))); var sl =browser.FindElement(By.Id("ctl00_SampleContent_DropDownList1")); var l = new SelectElement(sl); l.SelectByText("Acura"); w.Until(ExpectedConditions.ElementExists(By.XPath("id('ctl00_SampleContent_DropDownList2')/option[text()='Integra']"))); sl = browser.FindElement(By.Id("ctl00_SampleContent_DropDownList2")); l = new SelectElement(sl); l.SelectByText("Integra"); w.Until(ExpectedConditions.ElementExists(By.XPath("id('ctl00_SampleContent_DropDownList3')/option[text()='Sea Green']"))); sl = browser.FindElement(By.Id("ctl00_SampleContent_DropDownList3")); l = new SelectElement(sl); l.SelectByText("Sea Green"); w.Until(ExpectedConditions.ElementExists(By.XPath("//span[@id='ctl00_SampleContent_Label1' and text()='You have chosen a Sea Green Acura Integra. Nice car!']"))); browser.Quit(); } Setup
46. [Test] public void one_method_to_rule_them_all() { var profile = new FirefoxProfile(); var exe = new FirefoxBinary(@"D:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe"); IWebDriver browser = new FirefoxDriver(exe, profile); WebDriverWait w = new WebDriverWait(browser,TimeSpan.FromSeconds(10)); browser.Navigate().GoToUrl("http://localhost/AJAXDemos/CascadingDropDown/CascadingDropDown.aspx"); //browser.Navigate().GoToUrl("http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/CascadingDropDown/CascadingDropDown.aspx"); w.Until(ExpectedConditions.ElementExists(By.XPath("id('ctl00_SampleContent_DropDownList1')/option[text()='Acura']"))); var sl =browser.FindElement(By.Id("ctl00_SampleContent_DropDownList1")); var l = new SelectElement(sl); l.SelectByText("Acura"); w.Until(ExpectedConditions.ElementExists(By.XPath("id('ctl00_SampleContent_DropDownList2')/option[text()='Integra']"))); sl = browser.FindElement(By.Id("ctl00_SampleContent_DropDownList2")); l = new SelectElement(sl); l.SelectByText("Integra"); w.Until(ExpectedConditions.ElementExists(By.XPath("id('ctl00_SampleContent_DropDownList3')/option[text()='Sea Green']"))); sl = browser.FindElement(By.Id("ctl00_SampleContent_DropDownList3")); l = new SelectElement(sl); l.SelectByText("Sea Green"); w.Until(ExpectedConditions.ElementExists(By.XPath("//span[@id='ctl00_SampleContent_Label1' and text()='You have chosen a Sea Green Acura Integra. Nice car!']"))); browser.Quit(); } Commented Out Code!
47. [Test] public void one_method_to_rule_them_all() { var profile = new FirefoxProfile(); var exe = new FirefoxBinary(@"D:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe"); IWebDriver browser = new FirefoxDriver(exe, profile); WebDriverWait w = new WebDriverWait(browser,TimeSpan.FromSeconds(10)); browser.Navigate().GoToUrl("http://localhost/AJAXDemos/CascadingDropDown/CascadingDropDown.aspx"); //browser.Navigate().GoToUrl("http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/CascadingDropDown/CascadingDropDown.aspx"); w.Until(ExpectedConditions.ElementExists(By.XPath("id('ctl00_SampleContent_DropDownList1')/option[text()='Acura']"))); var sl =browser.FindElement(By.Id("ctl00_SampleContent_DropDownList1")); var l = new SelectElement(sl); l.SelectByText("Acura"); w.Until(ExpectedConditions.ElementExists(By.XPath("id('ctl00_SampleContent_DropDownList2')/option[text()='Integra']"))); sl = browser.FindElement(By.Id("ctl00_SampleContent_DropDownList2")); l = new SelectElement(sl); l.SelectByText("Integra"); w.Until(ExpectedConditions.ElementExists(By.XPath("id('ctl00_SampleContent_DropDownList3')/option[text()='Sea Green']"))); sl = browser.FindElement(By.Id("ctl00_SampleContent_DropDownList3")); l = new SelectElement(sl); l.SelectByText("Sea Green"); w.Until(ExpectedConditions.ElementExists(By.XPath("//span[@id='ctl00_SampleContent_Label1' and text()='You have chosen a Sea Green Acura Integra. Nice car!']"))); browser.Quit(); } Duplication
48. [Test] public void one_method_to_rule_them_all() { var profile = new FirefoxProfile(); var exe = new FirefoxBinary(@"D:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe"); IWebDriver browser = new FirefoxDriver(exe, profile); WebDriverWait w = new WebDriverWait(browser,TimeSpan.FromSeconds(10)); browser.Navigate().GoToUrl("http://localhost/AJAXDemos/CascadingDropDown/CascadingDropDown.aspx"); //browser.Navigate().GoToUrl("http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/CascadingDropDown/CascadingDropDown.aspx"); w.Until(ExpectedConditions.ElementExists(By.XPath("id('ctl00_SampleContent_DropDownList1')/option[text()='Acura']"))); var sl =browser.FindElement(By.Id("ctl00_SampleContent_DropDownList1")); var l = new SelectElement(sl); l.SelectByText("Acura"); w.Until(ExpectedConditions.ElementExists(By.XPath("id('ctl00_SampleContent_DropDownList2')/option[text()='Integra']"))); sl = browser.FindElement(By.Id("ctl00_SampleContent_DropDownList2")); l = new SelectElement(sl); l.SelectByText("Integra"); w.Until(ExpectedConditions.ElementExists(By.XPath("id('ctl00_SampleContent_DropDownList3')/option[text()='Sea Green']"))); sl = browser.FindElement(By.Id("ctl00_SampleContent_DropDownList3")); l = new SelectElement(sl); l.SelectByText("Sea Green"); w.Until(ExpectedConditions.ElementExists(By.XPath("//span[@id='ctl00_SampleContent_Label1' and text()='You have chosen a Sea Green Acura Integra. Nice car!']"))); browser.Quit(); } Can you read this? No? Didn’t think so.
50. Testable User Interfaces
54. Better Testing
55. Testers can help Devs
56. Improved acceptance criteria
57. Good Test Case design
58. Payroll System: Rate * Hours == Wages Hours > 40 == Hours* 1.5
59. 40 hours, 5 rate == 200 41 hours, 5 rate == 207.5 DONE! Dev Tester What about zero? Fine. 40 hours, 5 rate == 200 41 hours, 5 rate == 207.5 0 hours, 5 rate == 0 1 hour, 0 rate == 0 What about negatives? Whatever. 40 hours, 5 rate == 200 41 hours, 5 rate == 207.5 0 hours, 5 rate == 0 1 hour, 0 rate == 0 -1 hour, 1 rate == Exception 1 hour, -1 rate == Exception What about changing rates during period?
60. Dev Tester Go away
