我发现使用testthat
. 运行时test_file
,会发现单独test_that
的调用,但除了上下文名称之外没有输出到控制台,并且返回data.frame
的结果没有预期的结果。我怀疑我在做一些非常愚蠢的事情,但尝试了很多替代方案并得到了相同的结果。
这是我的tests.r
文件:
context("The context")
test_that('should pass',function(){
expect_equal(42,42)
})
test_that('should fail',function(){
expect_equal(43,42)
})
test_that('should error',function(){
stop()
})
我运行test_file
它:
> require(testthat)
Loading required package: testthat
> test_file('tests.r')
The context :
> results <- test_file('tests.r')
The context :
> results
file context test nb failed error user system real
1 tests.r The context should pass 0 0 FALSE 0 0 0.002
2 tests.r The context should fail 0 0 FALSE 0 0 0.001
3 tests.r The context should error 0 0 FALSE 0 0 0.001
如您所见,没有控制台输出,并且在结果data.frame
中没有一个失败的测试和一个有错误的测试,看起来好像一切都通过了。
当我直接在控制台中运行函数体时,我得到了预期的结果:
> expect_equal(42,42)
> expect_equal(43,42)
Error: 43 not equal to 42
Mean relative difference: 0.02380952
> stop()
Error:
这就是我正在运行的:

怀疑我的安装可能有问题,或者我在 Ubuntu Trusty/R 3.12 和 Windows 7/R 3.11 上尝试了相同的测试并得到相同的结果。我真的一定是在做蠢事!
当我使用以下方法编写类似测试时Runit
:
test.should_pass <- function(){
checkEquals(42,42)
}
test.should_fail <- function(){
checkEquals(43,42)
}
test.should_error <- function(){
stop()
}
我得到了预期的输出和结果:
> results <- runTestFile('tests.r')
Executing test function test.should_error ... Timing stopped at: 0 0 0
Error in func() :

Executing test function test.should_fail ... Timing stopped at: 0 0 0.001
