Intellij find all test coverage for a class - intellij-idea

I found a really nice set of functionality in IntelliJ but it is very manual...
use Analyze/Analyze backward dependencies on a object to find all the tests that eventually reference that class.
Create a run configuration using Test Kind "Pattern" and manually enter each of the test classes found into the "Pattern" field.
Run the test with code coverage
Navigate to the original class to view it's total test coverage.
This whole process is fairly slow and user intensive, but it could easily be automated with a single "Find test coverage for class" key-press (It would still be pretty slow, but I could go on and do something else). Does anyone know if this is in a key binding or plug-in I haven't found yet? It seems like a pretty obviously useful and easy to implement piece of functionality.
If not, can anyone suggest how I might do this with the IDE scripting console or a custom Intention (I've had no success finding really good usable documentation/examples of the IDE scripting console, haven't looked into intentions too much...)

How about the following 2 flows/options based on the Windows shortcuts (don't mind the failing stuff, it's just a quick copy-paste for the sake of brevity):
1) With the cursor placed on your class name:
CTRL+SHIFT+T (Chose test for launch)
SHIFT+END (Select all)
SHIFT+UP (Unselect Create new test...)
CTRL+SHFIT+F10 (Execute selected tests)
2) With the Group by test/production option selected in the find window and cursor placed on your class name:
ALT+F7 (Find usages)
chose the tests from the list
CTRL+SHFIT+F10 (Execute selected tests)

Show me your ID(E)!

I often work on very small pieces of code, on the order of max 100 lines, especially in scenarios when I learn something new and just play with the code, or when I debug.
Because I frequently change code and want to see how that changes the contents of my variables and output, it is tedious to either
1) hit the debug button, wait for the debugger to start (in my case I use PyCharm as an IDE) and then inspect the output
or
2) insert some prints for the variables that I want to observe and compile the code (slightly faster than starting the debugger).
To eliminate this time consuming workflow, where I constantly hit the compile or debug button every few seconds, is there an IDE where I can set a watch to a few variables and then each time I change in my source code a single character (or, alternatively, every half a second) the IDE automatically compiles everything and I will see then new values of my variables?
(Of course while I intermediatelychange the code the compilation will give errors, but that is ok. This feature would be a big time saver. Maybe PyCharm has it already implemented? If not, ideally I would hope for a language agnostic IDE, similar to PyCharm, where variants for Java etc. also exist. If not, since I code in Python, a Python IDE would also be great.)
This might not be exactly what you are looking for but PyCharm (and IntelliJ and probably others) can run tests automatically when code changes.
In the PyCharm Run toolbar look for "Toggle auto-test" button.
For example in PyCharm you can create test cases that just runs the code you're interested in and prints the variables you need.
Then create a run configuration that runs only those tests and set it to run automatically.
For more details see PyCharm documentation on rerunning tests.
The Scala plugin for IntelliJ has exactly what you need in the form of "worksheets," where every expression is automatically recompiled when its value or the value of anything it references is changed.
Since (based on your usage of PyCharm), I assume you're using Python primarily, I think Jupyter notebook is your best bet. Jupyter is language agnostic but began as specific to python (it was called IPython notebook for this reason).
I have not tried it, but this guide purports to show to get Jupyter to work with PyCharm
EDIT: Here is another possibility called vim worksheet; I haven't tried it, but it purports to do the same thing as Scala worksheets, but in vim, and for a number of languages, including Python.
The python Spyder IDE (comes with Anaconda) has this feature. When you hit run, you can see all of the variables at the top right of the screen and you can click on them to see their values (this is very helpful with Numpy Arrays too!).
If your interest is in the actual workflow improvement:
I used to program like you, looking at what my variables changed to, and design or debug my code based on such modifications, however is way to inefficient and costly to set what variables to watch over and over again and besides when if it bugs, you have to go all over again for the debugging process.
I changed my design process to better my workflow and adopted Test Driven Development (TDD), with it you can look at tools for you specific implementations or IDEs but the principles and workflow stay with you, with it you stop looking on how the variables changed and instead focus on what the functions should do, meaning faster iteration (with real time tools for testing), easier debugging and far more better, safe refactoring.
My favorite tool for it is Cucumber, and agnostic tool (for IDE or programming language) which help you test your code scenarios and at the same time documenting your features.
Hope it helps, i know its a very opinionated answer but it's an honest advices for improvement in ones workflow.
You should try Thonny. It is developed by Institute of Computer Science of University of Tartu.
The 4 features which might be of help to you are below (verbatim from the website):
No-hassle variables.
Once you're done with hello-worlds, select View → Variables and see how your programs and shell commands affect Python variables.
Simple debugger.
Just press Ctrl+F5 instead of F5 and you can run your programs step-by-step, no breakpoints needed. Press F6 for a big step and F7 for a small step. Steps follow program structure, not just code lines.
Stepping through statements
Step through expression evaluation. If you use small steps, then you can even see how Python evaluates your expressions. You can think of this light-blue box as a piece of paper where Python replaces subexpressions with their values, piece-by-piece.
Visualization of expression evaluation
Faithful representation of function calls.
Stepping into a function call opens a new window with separate local variables table and code pointer. Good understanding of how function calls work is especially important for understanding recursion.

Replicate class with main method as in Java IDE within Objective-C and Xcode 4

I have a simple question. Coming from a java background and having worked extensively with eclipse, netbeans or any other java IDE, is quite nice to have the possibility to add a main method to a class and execute it within the IDE, with just a click, and see the output.
I was looking for the same possibility within xcode4/objective-c but I couldn't find a way. From time to time, I like testing small piece of software, without compiling and running the whole project.
As I am still "thinking" in Java, could you suggest the proper way to achieve this with xcode4 from an "objective-c developer point of view" ?
thanks
There's not really a lightweight way to do this, but you have two options that I can think of depending on whether you want to keep the harness code you've written.
If you do, then you'd need to make a new target in your project for each class you drive with a harness, and have that target build just the class you are driving and a simple file with just the main code to drive that class.
If you don't, then you could make a target with a main, and each time you want to drive a different class, change which files are built, change the code in main, and rebuild.
This is assuming that you want to avoid both running and compiling the rest of your code. If you don't mind compiling everything, you could have one test-harness target that builds all of your classes, and either change main on the fly, or use #ifdefs or a runtime argument to decide which helper code to run.

All the tests of the same category show up as only one test result w/ TestNG in Intellij and I'd like it not to happen. How?

I have been developing a project which contains a TestLauncher class that'll read a given directory and for each file it contains, run it against my tool and yield the results.
So, when coding in Eclipse, it would show up one result for each test (as expected). Today I've been toying with Intellij, and I've decided to try to run and code a bit of this project in Intellij.
When trying to run the tests, though, it seems to be only showing up 2 results instead of the 100+ it should. Although I am sure it is running the full suite, it seems to be folding all the results of a given category in a single result. That means that if I have at least one failing test in each category, it shows up as a "failed test".
I guess this must not be a bug, but rather some configuration that I am not aware about and that is on by default in Intellij but not in Eclipse. Could anyone explain what might be going on?
Edit: I am using the latest Intellij (downloaded one of these days).
Thanks
What you're seeing is simply a difference in the way the Eclipse and IDEA plug-ins are implemented. I implemented the Eclipse plug-in to be pretty clever in its display, so it will show different things depending on various factors such as the presence of a toString() method in your test class or whether your test class implements org.testng.ITest.
I suggest you ask this question on the IDEA forums and if you don't get any response, feel free to email the testng-users list and I can put you in touch with the JetBrains engineer in charge of the TestNG plug-in.
The IntelliJ-IDEA TestNG Plugin has a filter symbol called "Hide Passed" above the output Test Results. You can toggle that to display all tests, including the passed ones.

how can I add code reuse to my Selenium tests?

Here's the situation that I'm working with:
Build tests in Selenium
Get all the tests running correctly (in Firefox)
Export all the tests to MSTest (so that each test can be run in IE, Chrome and FF)
If any test needs to be modified, do that editing in Selenium IDE
So it's a very one-way workflow. However, I'd now like to do a bit more automation. For instance, I'd like every test to run under each of two accounts. I'm getting into a maintenance issue. If I have 6 tests that I want to run under two accounts, suddenly I'd need 12 tests in the Selenium IDE tests. That's too much editing. But a ton of that code is exactly the same.
How can I share chunks of Selenium tests among tests? Should I use Selenium IDE to develop the test first time then never use it again (only doing edits in VS after that)?
Selenium code is very linear after you export it from the IDE.
For example (ignore syntax):
someTestMethod() {
selenium.open("http://someLoginPage.com");
selenium.type("usernameField", "foo");
selenium.type("passwordField", "bar");
selenium.click("loginButton");
selenium.waitForPageToLoad("30000");
assertTrue(selenium.isTextPresent("Welcome * foo"));
}
This is the login page. Every single one of your tests will have to use it. You should refactor it into a method.
someTestMethod(){
selenium.open("http://someLoginPage.com");
String username = "foo";
String password = "bar";
performLogin(username, password);
}
performLogin(String username, String password){
selenium.type("usernameField", username);
selenium.type("passwordField", password);
selenium.click("loginButton");
selenium.waitForPageToLoad("30000");
assertTrue(selenium.isTextPresent("Welcome * foo"));
}
The performLogin() method does not have to be in the same file as your test code itself. You can create a separate class for it with your methods and share it between your tests.
We have classes that correspond to certain functionalities on our UI. For example, we have many ways to search in our app. All methods that helps you with search functionality will be in the SearchUtil class.
Structuring your tests similarly will give you the following advantages:
If the UI changes (an id of a field), you go to your one method, update the id and you are good to go
If the flow of your logic changes you also have only one place to update
To test whether your changes worked, you only have to run one of the tests to verify. All other tests use the same code so it should work.
A lot more expressive as you look at the code. With well named methods, you create a higher level of abstraction that is easier to read and understand.
Flexible and extensible! The possibilities are limitless. At this point you can use conditions, loops, exceptions, you can do your own reporting, etc...
This website is an excellent resource on what you are trying to accomplish.
Good Luck!
There are two aspects to consider regarding code reuse:
Eliminating code duplication in your own code base -- c_maker touched on this.
Eliminating code duplication from code generated by Selenium IDE.
I should point out that my comments lean heavily to the one-way workflow that you are using, jcollum, but even more so: I use IDE to generate code just once for a given test case. I never go back to the IDE to modify the test case and re-export it. (I do keep the IDE test case around as a diagnostic tool when I want to experiment with things while I am fine-tuning and customizing my test case in code (in my case, C#).
The reasons I favor using IDE tests only as a starting point are:
IDE tests will always have a lot of code duplication from one test to another; sometimes even within one test. That is just the nature of the beast.
In code I can make the test case more "user-friendly", i.e. I can encapsulate arcane locators within a meaningful-named property or method so it is much clearer what the test case is doing.
Working in code rather than the IDE just provides much greater flexibility.
So back to IDE-generated code: it always has massive amounts of duplication. Example:
verifyText "//form[#id='aspnetForm']/div[2]/div/div[2]/div[1]/span" Home
generates this block of code:
try
{
Assert.AreEqual("Home",
selenium.GetText("//form[#id='aspnetForm']/div[2]/div/div[2]/div[1]/span"));
}
catch (AssertionException e)
{
verificationErrors.Append(e.Message);
}
Each subsequent verifyText command generates an identical block of code, differing only by the two parameters.
My solution to this pungent code smell was to develop Selenium Sushi, a Visual Studio C# project template and library that lets you eliminate most if not all of this duplication. With the library I can simply write this one line of code to match the original line of code from the IDE test case:
Verify.AreEqual("Home",
selenium.GetText("//form[#id='aspnetForm']/div[2]/div/div[2]/div[1]/span"));
I have an extensive article covering this (Web Testing with Selenium Sushi: A Practical Guide and Toolset) that was just published on Simple-Talk.com in February, 2011.
You can also put some fragments or one-liners, e.g.
note( "now on page: " . $sel->get_location() . ", " . $sel->get_title() ;
into the "code snippets" collection of your IDE ( I use Eclipse).
That's not true reuse, but hey it works for me for throwaway testscripts or quick enhancements of existing testscripts.

TestCase scripting framework

For our webapp testing environment we're currently using watin with a bunch of unit tests, and we're looking to move to selenium and use more frameworks.
We're currently looking at Selenium2 + Gallio + Xunit.net,
However one of the things we're really looking to get around is compiled testcases. Ideally we want testcases that can be edited in VS with intellisense, but don't require re-compilling the assembly every single time we make a small change,
Are there any frameworks likely to help with this issue?
Are there any nice UI tools to help manage massive ammount of testcases?
Ideally we want the testcase writing process to be simple so that more testers can aid in writing them.
cheers
You can write them in a language like ruby (e.g., IronRuby) or python which doesnt have an explicit compile step of such a manner.
If you're using a compiled a compiled language, it needs to be compiled. Make the assemblies a reasonable size and a quick Shift F6 (I rewire it to shift Ins) will compile your current project. (Shift Ctrl-B will typically do lots of redundant stuff). Then get NUnit to auto-re-run the tests when it detects the assembly change (or go vote on http://xunit.codeplex.com/workitem/8832 and get it into the xunit GUI runner).
You may also find that CR, R# and/or TD.NET have stuff to offer you in speeding up your flow. e.g., I believe CR detects which tests have changed and does stuff around that (at the moment it doesnt support the more advanced xunit.net testing styles so I dont use it day to day)
You wont get around compiling test frameworks if you add new tests..
However there are a few possibilities.
First:
You could develop a native language like i did in xml or similar format. It would look something like this:
[code]
action name="OpenProfile"
parameter name="Username" value="TestUser"
[/code]
After you have this your could simply take an interpreter and serialize this xml into an object. Then with reflection you could call the appropriate function in the corresponding class. After you have a lot of actions implemented of course perfectly moduled and carefully designed structure ( like every page has its own object and a base object that every page inherits from ), you will be able to add xml based tests on your own without the need of rebuilding the framework it self.
You see you have actions like, login, go to profile, go to edit profile, change password, save, check email etcetc. Then you could have tests like: login change password, login edit profile username... and so on and so fort. And you only would be creating new xmls.
You could look for frameworks supporting similar behavior and there are a few out there. The best of them are cucumber and fitnesse. These all support high level test case writing and low level functionality building.
So basically once you have your framework ready all your have to do is writing tests.
Hope that helped.
Gergely.
