如何测试具有多个输入/预期输出的功能?
这是一个非常简单的例子:
scenario "Can add two numbers", {
given "Two numbers", {
num1 = 2
num2 = 3
}
when "I trigger add.", {
result = add(num1,num2)
}
then "The result should be correct.", {
result.shouldBe 5
}
}
我想用多个值来测试它,比如add(4,8).shouldBe 12, ....
这样做的最佳做法是什么?在其他BDD框架中,我已经看到了表格式结构来实现这一点,但在EasyB中找不到类似的东西。我应该创建多个场景来覆盖它(将(1),(2)附加到场景名称),还是应该将输入和预期输出放入数组中,并检查它是否相等? 如果我使用后一种方法,我如何得到有意义的失败?

使用where / example子句 http://code.google.com/p/easyb/wiki/ChangesInEasyb098
package org.easyb.where
/*
Example tests a map at the story level
*/
numberArray = [12, 8, 20, 199]
where "we are using sample data at a global level", [number:numberArray]
before "Before we start running the examples", {
given "an initial value for counters", {
println "initial"
whenCount = 0
thenCount = 0
numberTotal = 0
}
}
scenario "Number is #number and multiplier is #multiplier and total is #{number * multiplier}", {
when "we multiply #number by #multiplier", {
whenCount ++
num = number * multiplier
}
then "our calculation (#num) should equal #{number * multiplier}", {
num.shouldBeGreaterThan 0
numberTotal += num
thenCount ++
}
where "Multipliers should be", {
multiplier = [1,2,3]
}
}
after "should be true after running example data", {
then "we should have set totals", {
whenCount.shouldBe 12
thenCount.shouldBe 12
num = 0
numberArray.each { n ->
num = num + (n + (2*n) + (3*n))
}
num.shouldBe numberTotal
}
}
