I'm using Emacs and trying to get my unit testing work flow as automated as possible. I have it set up so it is working but I have to manually compile my module under test or the module containing the tests before the Erlang Shell recognizes my changes.
I have two files mymodule.erl and mymodule_tests.erl. What I would like to be able to do is:
Add test case to mymodule_tests
Save mymodule_tests
Switch to the Erlang Shell
Run tests with one line, like eunit:test(mymodule) or mymodule_tests:test()
Have Erlang reload mymodule and mymodule_tests before actually performing the tests
I have tried writing my own test method but it doesn't work.
-module (mytests).
-export([test/0]).
-import(mymodule).
-import(mymodule_tests).
-import(code).
test() ->
code:purge(mymodule),
code:delete(mymodule),
code:load_file(mymodule),
code:purge(mymodule_tests),
code:delete(mymodule_tests),
code:load_file(mymodule_tests),
mymodule_tests:test().
I have also tried by putting -compile(mymodule). into mymodule_tests to see if I could get mymodule to automatically reload when updating mymodule_tests but to no avail.
I have also googled quite a bit but can't find any relevant information. As I'm new to Erlang I'm thinking that I'm either searching for the wrong terms, e.g. erlang reload module, or that you are not supposed to be able reload other modules when compile another module.
Maybe the Erlang make can help you.
make:all([load]).
Reading from the doc:
This function first looks in the
current working directory for a file
named Emakefile (see below) specifying
the set of modules to compile and the
compile options to use. If no such
file is found, the set of modules to
compile defaults to all modules in the
current working directory.
And regarding the "load" option:
Load mode. Loads all recompiled
modules.
There's also a make:files/1,2 which allows you to specify the list of modules to check.
Have you tried using l(mymodule). to reload the module after it's been compiled?

In the Jest tests for my React app in WebStorm, the following line
const { createMemoryHistory } = require("history");
has the following warning:
Module is not listed in package.json dependencies
The tests run as expected, they pass and fail as expected. createMemoryHistory works. And when I hover on history WebStorm actually shows me the documentation for the library.
(strike this:) But history is a native JS library, like fs, is it not? How do I fix this pesky warning?
UPDATE: Okay, I understand that fs is not a native JS library, it's a core node.js module. I was wrong and thanks for setting me straight on that.
I see that my package-lock.json does include an entry for "node_modules/history". It looks like it's two indents deep, but the lockfile is too complex for me to really tell, or get breadcrumbs, or fold the branch to see where this line falls in the tree.
So I guess the real question is, Webstorm is saying that I don't have the dependency, but the lockfile implies that I do. Unless I'm misunderstanding further.
Again, how do I fix this pesky warning? (or what other fact am I missing? Remember, everything does actually work).
fs is a core Node.js module, i.e. its code is compiled into Node.js binary and doesn't have to be installed. history library is a usual NPM module that is not a part of Node.js core and has to be added with npm i history(see https://github.com/remix-run/history/blob/main/docs/installation.md). The IDE just tells you that you are importing a module that is not listed among dependencies in your package.json
I am new to Odoo. I am using Odoo 10. I would like to write test cases for a new wizard I created under a module A. I put all my wizard code (views + models) inside wizards directory. I created unit test cases under the path <<module/tests>> followed all the file/class/method naming conventions. When I try to upgrade the module (with test enable) to run unit test cases, all the other modules tests scripts are run but not for the newly created module A. Please suggest what additional changes might be needed to enable test scripts for a newly created module with wizard.
Thank you.
I believe that the structure you have follow is according to the standard way. You can find the structure here Testing Module Structure.
Also please check that the naming on the folder and file in which you wrote the code,
for example - tests/test_todo.py Also, don't forget to update the import in tests/init.py to from. import test_todo
This is because Odoo expects the test module names to start with test_ when it searches for tests belonging to a module Code Reference
Command to Run the testcases:
python ./odoo.py -i module_to_test --log-level=test -d your_database --db-filter=your_database --test-enable --stop-after-init
Are there julia libraries that can run unittests automatically when I make changes to the code?
In Python there is the pytest.xdist library which can run unittests again when you make changes to the code. Does julia have a similar library?
A simple solution could be made using the standard library module FileWatching; specifically FileWatching.watch_file. Despite the name, it can be used with directories as well. When something happens to the directory (e.g., you save a new version of a file in it), it returns an object with a field, changed, which is true if the directory has changed. You could of course combine this with Glob to instead watch a set of source files.
You could have a separate Julia process running, with the project's environment active, and use something like:
julia> import Pkg; import FileWatching: watch_file
julia> while true
event = watch_file("src")
if event.changed
try
Pkg.pkg"test"
catch err
#warn("Error during testing:\n$err")
end
end
end
More sophisticated implementations are possible; with the above you would need to interrupt the loop with Ctrl-C to break out. But this does work for me and happily reruns tests whenever I save a file.
If you use a Github repository, there are ways to set up Travis or Appveyor to do this. This is the testing method used by many of the registered modules for Julia. You will need to write the unit test suite (with using Test) and place it in a /test subdirectory on the github repository. You can search for julia and those web services for details.
Use a standard GNU Makefile and call it from various places depending on your use-case
Your .juliarc if you want to check for tests on startup.
Cron if you want them checked regularly
Inside your module's init function to check every time a module is loaded.
Since GNU makefiles detect changes automatically, calls to make will be silently ignored in the absence of changes.
So I am running into an issue when I go to build my projects using tfs build controller using the Output location "AsConfigred" it will not detect my unit tests. Let me give a little info on my setup.
TFS 2013 Update 2, Default Process Template
Here is a few screenshots that can hopefully help fill in what I can't in typing. I am copying my build out to a file share on our network so that we can use other utilities use the output. I don't want to use "PerProject" or "SingleFolder" because they mess up the file structure we have configured (These both will run the tests). So i have the files copy to folder names "SingleOutputFolder" which is a child of the DropLocation. I would like to be able to run from the drop folder or run from the bin folder for each of my tests (I don't care which). However it doesn't seem to detect/run ANY of the tests. Any help would be greatly appreciated. Please let me know if you need any additional information.
I have tried using ***test*.dll, Install\SingleFolderOutput**.test.dll, and $(TF_BUILD_DROPLOCATION)\Install\SingleFolderOutput*test*.dll
But I am not sure what variables are available and understand where the scope of its execution is.
Given that you're using Build Output location set to AsConfigured you have to change the default values of the Test sources spec setting to allow build to find the test libraries in the bin folders. Here's an example.
If the full path to the unit test libraries is:
E:\Builds\7\<TFS Team Project>\<Build Definition>\src\<Unit Test Project>\bin\Release\*test*.dll
use
..\src\*UnitTest*\bin\*\*test*.dll;
This question was asked on MSDN forums here.
MSDN Forums Suggested Workaround
The suggested workaround in the accepted answer (as of 8 a.m. on June 20) is to specify the full path to the test projects' binary folders: For example:
C:\Builds\{agentId}\{teamProjectName}\{buildDefinitionName}\src\{solutionName}\{testProjectName}\bin*\Debug\*test*.dll*
which really should have been shown as
{agentWorkingFolder}\src\{relativePathToTestProjectBinariesFolder}\*test*.dll
However this approach is very brittle, for the following reasons:
Any new test projects you add to the solution will not be executed until you add them to the build definition's list of test sources:
It will break under any of the following circumstances:
the build definition is renamed
the working folder in build agent properties is modified
you have multiple build agents, and a different agent than the one you specified in {id} runs the build
Improved Workaround
My workaround mitigates the issues listed in #2 (can't do anything about #1).
In the path specified above, replace the initial part:
{agentWorkingFolder}
with
..
so you have
..\src\{relativePathToTestProjectBinariesFolder}\*test*.dll
This works because the internal working directory is apparently the \binaries\ folder that is a sibling of the \src\ folder. Navigating up to the parent folder (whatever it is named, we don't care) and back in to \src\ before specifying the path to the test projects binaries does the trick.
Note: If you have multiple test projects, you add additional entries, separated with semicolons:
..\src\{relativePathToTestProjectONEBinariesFolder}\*test*.dll;..\src\{relativePathToTestProjectTWOBinariesFolder}\*test*.dll;..\src\{relativePathToTestProjectTHREEBinariesFolder}\*test*.dll;
What I ended up doing was adding a post build event to copy all of the test.dll into the staging location folder in the specific build that is basically equivalent to where it would go on a SingleFolder build and do that on each test project.
if "$(TeamBuildOutDir)" == "" (
echo "Building Interactively not in TFS"
) else (
echo "Building in TFS"
xcopy "$(TargetDir)*.*" "$(TeamBuildBinaries)\" /Y /E /S
)
MSBUILD parameter in the build def that told it to basically drop in the folder that TFS looks for them.
/p:TeamBuildBinaries="$(TF_BUILD_BINARIESDIRECTORY)"
Kept the default Test assembly file specification:
**\*test*.dll
View this link for the information on the variable that I used and what relative path it exists at.
Another solution is to do the reverse.
Leave all of the files in the root so that all of the built in functionality works. There is more than just test execution in there. What about static code analysis, impact analysis..among others. You would have to do something custom for them all.
Instead use a pre-drop powershell script to create your Install arrangement from the root files.
If it is an application then you can use the _ApplicationFolder Nuget package to create an _PublishApplications folder same as you get for web applications.
I have an error similar to the one in this post. Now, I'm sure I've made some stupid error somewhere, probably related to releasing an object or an observer or what-not, but since I can't seem to find a way to debug the code I thought I could use the NSDebugEnabled, NSZombieEnabled and MallocStackLogging (as shown here).
Can it be done using OCUnit? If so, how? I just can't find an "executable" to set these parameters on...
Thanks!
Aviad.
Unfortunately, Dave's solution didn't work - I kept getting errors and mistakes. I eventually got GHUnit to work on my project, found the problem by debugging, but it had its own problems so I now use both it and OCUnit which is slightly better integrated in terms of showing the results in the results tab.
sigh. When will we get to see a good, complete unit testing framework for Obj-C?
This may have been fixed in recent Xcodes, but I get zombies by doing
Go into schemes (cmd <)
Open Test, then Arguments tab
Uncheck "Use the Run action's arguments and environment variables"
"+" an environment variable "NSZombieEnabled" = "YES"
Well, NSZombieEnabled and friends are environment variables, which means they have to be run on an executable. The default setup for a unit testing bundle is for the tests to be run during the build process, and not during execution.
So the way to fix this is to make it so that your tests don't run during the build phase, but instead run them as part of an executable.
Here's how I do that:
Inside your Unit Test bundle target, remove the "Run Script" build phase. It's that step that executes the tests after compiling them.
From the Project menu, choose "New Custom Executable..." and name it something meaningful, like "otest"
Make the executable path to be the otest binary, which should be located at /Developer/Tools/otest
Set the following environment variables on the otest executable:
DYLD_FRAMEWORK_PATH => {UnitTest.bundle}/Contents/Frameworks
DYLD_LIBRARY_PATH => {UnitTest.bundle}/Contents/Frameworks
Set the following program arguments on the otest executable:
-SenTest All (this will run all of the unit tests)
{UnitTest.bundle}
You can now select your unit test bundle as the active target, and the otest executable as the active executable, and then build and debug. This will let you set breakpoints, set other environment variables (like NSZombieEnabled), and so on.
If you only want to debug a certain suite or specific unit test, you can change the -SenTest All argument to -SenTest MyUnitTestSuite or -SenTest MyUnitTestSuite/myUnitTestMethod.
It took me quite some time but I finally managed to make it work for my project.
To create the "logic" tests I followed Apple guidelines on creating logic tests.
This works fine once you understand that the logic tests are run during build.
To be able to debug those tests it is required to create a custom executable that will call those tests. The article by Sean Miceli on the Grokking Cocoa blog provides all the information to do this. Following it however did not yield immediate success and needed some tweaking.
I will go over the main steps presented in Sean's tutorial providing some "for dummies" outline which took me some time to figure out:
Setup a target that contains the unit tests but DOES NOT run them
Setup the otest executable to run the tests
Setup the otest environment variables so that otest can find your unit tests
Step 1 - Setting up the target
Duplicate your unit tests target located under your project Targets. This will also create a duplicate of your unit tests product (.octest file). In the figure below "UnitTest" is the original target.
Rename both the unit tests target and the unit tests product (.octest file) to the same name. In the figure below "UnitTestsDebug" is the duplicate target.
Delete the RunScript phase of the new target
The name of both can be anything but I would avoid spaces.
Step 2 - Setting up otest
The most important point here is to get the correct otest, i.e. the one for your current iOS and not the default Mac version. This is well described in Sean's tutorial. Here are a few more details which helped me setting things right:
Go Project->New Custom Executable. This will pop open a window prompting you to enter an Executable Name and an Executable Path.
Type anything you wish for the name.
Copy paste the path to your iOS otest executable. In my case this was /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk/Developer/usr/bin/otest
Press enter. This will bring you to the configuration page of your executable.
The only thing to change at this point is to select "Path Type: Relative to current SDK". Do not type in the path, this was done at step 3.
Step 3 - Setting up the otest arguments and environment variables
The otest arguments are straightforward to setup... But this proved to be my biggest problem. I initially had named my logic test target "LogicTests Debug". With this name and "LogicTests Debug.octest" (with quotes) as argument to otest I kept having otest terminating with exit code 1 and NEVER stopping into my code...
The solution: no space in your target name!
The arguments to otest are:
-SenTest Self (or All or a test name - type man otest in terminal to get the list)
{LogicTestsDebug}.octest - Where {LogicTestsDebug} needs to be replaced by your logic test bundle name.
Here is the list of environment variables for copy/pasting:
DYLD_ROOT_PATH: $SDKROOT
DYLD_FRAMEWORK_PATH: "${BUILD_PRODUCTS_DIR}: ${SDK_ROOT}:${DYLD_FRAMEWORK_PATH}"
IPHONE_SIMULATOR_ROOT: $SDKROOT
CFFIXED_USER_HOME: "${HOME}/Library/Application Support/iPhone Simulator/User"
DYLD_LIBRARY_PATH: ${BUILD_PRODUCTS_DIR}:${DYLD_LIBRARY_PATH}
DYLD_NEW_LOCAL_SHARED_REGIONS: YES
DYLD_NO_FIX_PREBINDING: YES
Note that I also tried the DYLD_FORCE_FLAT_NAMESPACE but this simply made otest crash.
Step 4 - Running your otest executable
To run your otest executable and start debugging your tests you need to:
Set your active target to your unit test target (LogicTestsDebug in my case)
Set your active executable to your otest executable
You can build and run your executable and debug your tests with breakpoints.
As a side note if you are having problems running your otest executable it can be related to:
Faulty path. I had lots of problem initially because I was pointing to the mac otest. I kept crashing on launch with termination code 6.
Faulty arguments. Until I removed the space from bundle (.octest) name I kept having otest crash with exit code 1.
Wrong path in environment variables. [Sean tutorial][8] has lots of follow-up questions giving some insight on what other people tried. The set I have now seems to work so I suggest you start with this.
You may get some message in the console which might lead you to think something is wrong with your environment variables. You may notice a message regarding CFPreferences. This message is not preventing the tests from running properly so don't focus on it f you have problems running otest.
Last once everything is working you will be able to stop at breakpoints in your tests.
One last thing...
I've read on many blogs that the main limitation of the integrated XCode SenTestKit is that tests cannot be run while building the application. Well as it turns out this is in fact quite easy to manage. You simply need to add your Logic tests bundle as a dependency to your application project. This will make sure your logic tests bundle is built, i.e. all tests are run, before your application is built.
To do this you can drag and drop your logic test bundle onto your application target.
