How to run test cases in a specified file

Question

My package test cases are scattered across multiple files  if I run go test  lt package name gt  it runs all test cases in the package   It is unnecessary to run all of them though  Is there a way to specify a file for go test to run  so that it only runs test cases defined in the file

There are two ways  The easy one is to use the -run flag and provide a pattern matching names of the tests you want to run   Example     go test -run NameOfTest   See the docs for more info   The other way is to name the specific file  containing the tests you want to run     go test foo test go   But there s a catch  This works well if    foo go is in package foo  foo test go is in package foo test and imports  foo     If foo test go and foo go are the same package  a common case  then you must name all other files required to build foo test  In this example it would be     go test foo test go foo go   I d recommend to use the -run pattern  Or  where when possible  always run all package tests

zzzz s answer is mostly complete  but just to save others from having to dig through the referenced documentation you can run a single test in a package as follows   go test packageName -run TestName   Note that you want to pass in the name of the test  not the file name where the test exists   The -run flag actually accepts a regex so you could limit the test run to a class of tests  From the docs   -run regexp     Run only those tests and examples matching the regular     expression

When running a single test I usually do   go test -run TestSomethingReallyCool   folder1 folder2  -v -count 1   -count 1 also ensures that the test is ran every time instead of being cached  Useful when you are testing against race conditions and have a test that fails only sometimes  In Go versions not using modules the same could be achieved by setting GOCACHE off but this interacts poorly with Go modules

go test -v -timeout 30s  lt path to package gt  -run   TestFuncRegEx     The TestFunc must be inside a go test file in that package We can provide a regular expression to match a set of test cases or just the exact test case function to run a single test case  For instance -run TestCaseFunc

Visual Studio Code shows a link at the top of a Go test file which lets you run all the tests in just that file   In the  quot Output quot  window  you can see that it automatically generates a regex which contains all of the test names in the current file  Running tool  C  Go bin go exe test -timeout 30s -run   TestFoo TestBar TestBaz   rootpackage mypackage Note  the very first time you open a Go file in VS Code it automatically offers to install some Go extensions for you   I assume the above requires that you have previously accepted the offer to install
