同时获得两个属性的最佳方法

Question

假设您有分层数据，并且希望获得单独属性的合并值，那么最优雅的，或者说groovy的方法是什么呢？

def junitResultList = [
    [
        name: "Testsuite A",
        children: [
            failedTests: ["Test 1", "Test 2"],
            skippedTests: []
        ]
    ],
    [
        name: "Testsuite B",
        children: [
            failedTests: ["CursorTest"],
            skippedTests: ["ClickTest", "DragNDropTest"]
        ]
    ]
]

(junitResultList*.children*.failedTests + 
 junitResultList*.children*.skippedTests).flatten()

(junitResultList*.children*.findAll {
    ['skippedTests', 'failedTests'].contains(it.key)
})*.values().flatten()

Answer 1

您可以将初始表达式简化为如下所示：

junitResultList.children.collect { it.failedTests + it.skippedTests }.flatten()

或

junitResultList.children.collect { [it.failedTests, it.skippedTests] }.flatten()
