How do the names of methods affect execution of test cases in robotium?
Robotium seems to execute methods in a test class in alphabetical order. So if you precede the name of the methods by something like "test1...", test2..." etc, you can determine the proper order. However, the order should not matter for your test results. If it does, then your tests are not independent.
Methods prefixed with the name "test" are considered tests and are executed in alphabetical order. This is actually a functionality of JUnit, which the Android Test Framework is built on top of, and doesn't have anything to do specifically with Robotium.

Below is the structure how my Feature Files are divide. I have created Folders based on the functionalities and then added the scenarios inside them.
Now, I have to tag few test cases among them as Smoke Test cases and get them executed.
The point here is I need a specific order for that as in eg
Add Asset
Run Test
Schedule Test
Delete Asset
Since I will add something first and then work on it and delete it at the end
I know by default Cucumber executes test cases alphabetically but that would not solve my problem.
How can I achieve that?
I am using Java
Cucumber features/scenarios are run in Alphabetical order by feature file name.
However, if you specifically specify features, they should be run in the order as declared. For example:
#Cucumber.Options(features={"automatedTestingServices.feature", "smoketest.feature"})
You can achieve by setting priority or dependency, supported in QAF which is TestNg implementation for BDD. Setting priority with scenarion should do the needful for example:
with QAF scenario in DeleteAssets.feature may look like below:
#priority:100
#or you can set dependencies like below
##dependsOnGroups:['create','schedule']
#delete #otherGroup
Scenario: Delete existing Asset
Given ...
Note: gherkin syntax doesn't supports meta-data so you need to use either qaf bdd or bdd2 syntax and appropriate factory to run tests.
Yes, you can set a priority in cucumber scenarios. but not for the whole scenarios we can do that. inside methods we have declared in step definition file, can achieve that. Just put a keyword "Order" in the step definition file over the method based on the order of the method it will run as priority.

When I turn to project view, I can see percentages for a single class.
When I go inside, i cant see which methods are covered.
When i take export of results, and open in browser for HTML, I can see some green and red lines.
I can understand if a method has red or does not have any green, it does not have unit test.
But this is hard way.
Are there better ways here? Like: how can i find the unit test of a method if it has an unit test?
Answering on how can i find the unit test of a method if it has an unit test?
I think there is a misconception on your end. Nothing says that there is exactly one (or zero) unit test for a specific method.
It is rather common that there are multiple tests per production code method. For example to test the different results for different cases of input parameters.
It is also possible that a production code method gets executed when some "unrelated" test runs.
From that point of view, the "best" what you can do: select the production code method and have IntelliJ show you its usages. IntelliJ tells you in which module usages are found, and obviously: if the usage is within your unit test module, you know for sure: the method is used in the tests listed there.
But as said: that doesn't mean that other tests aren't running that method when doing their specific testing.
I have a questions on automation framework, Suppose i have 1000 test cases. I am adding a new test case in the middle.
e.g. I have 1000 test cases. I am adding a test case in the middle (501th). What are some of the issues i may faced in the framework?
-- I am expecting it may break the execution order if all 1000 TCs have some dependencies among themselves. Apart from this issue i am not able to figure out any other possible issues, please help me in identifying the issues that can cause problem in execution of all the TCs here.
You should never rely on the execution order of test cases.
Note that JUnit does not execute the test cases in the declared order - unless you use annotation #FixMethodOrder(MethodSorters.NAME_ASCENDING). Neither does testNG by default. Consequently, it does not really matter at which position you add the new test case.
Besides the changed execution order, you might encounter side effects if you
change static variables which are used by other test cases as well
change data in the database
create, change or delete files
close connections which are also used by other test cases
Can any one please tell me is there any kind of tools or eclipse base plugins available for generate relevant test cases for SalesForce platform related Apex classes. It seems with code coverage they are not expecting out come like we expect with JUnit, they want to cover whether, test cases are going through the flows of the source classes (like code go through).
Please don't get this post in wrong, I don't want anyone is going to write test cases for my codes :). I have post this question due to nature of SalesForce expecting that code coverage should be. Thanks.
Although Salesforce requires a certain percentage of code coverage for your test cases, you really need to be writing cases that check the results to ensure that the code behaves as designed.
So, even if there was a tool that could generate code to get 100% coverage of your test class, it wouldn't be able to test the results of those method calls, leaving you with a false sense of having "tested code".
I've found that breaking up long methods into separate, sometimes static, methods makes it easier to do unit testing. You can test each individual method, and not worry so much about tweaking parameters to a single method so that it covers all execution paths.
it's now possible to generate test classes automatically for your class/trigger/batch. You can install "Test Class Generator" app from AppExchange and see it working.
This would really help you generating test class and saves lot of your development time.
We use TestNG and Selenium WebDriver to test our web application.
Now our problem is that we often have several tests that need to run in a certain order, e.g.:
login to application
enter some data
edit the data
check that it's displayed correctly
Now obviously these tests need to run in that precise order.
At the same time, we have many other tests which are totally independent from the list of tests above.
So we'd like to be able to somehow put tests into "groups" (not necessarily groups in the TestNG sense), and then run them such that:
tests inside one "group" always run together and in the same order
but different test "groups" as a whole can run in any order
The second point is important, because we want to avoid dependencies between tests in different groups (so different test "groups" can be used and developed independently).
Is there a way to achieve this using TestNG?
Solutions we tried
At first we just put tests that belong together into one class, and used dependsOnMethods to make them run in the right order. This used to work in TestNG V5, but in V6 TestNG will sometimes interleave tests from different classes (while respecting the ordering imposed by dependsOnMethods). There does not seem to be a way to tell TestNG "Always run tests from one class together".
We considered writing a method interceptor. However, this has the disadvantage that running tests from inside an IDE becomes more difficult (because directly invoking a test on a class would not use the interceptor). Also, tests using dependsOnMethods cannot be ordered by the interceptor, so we'd have to stop using that. We'd probably have to create our own annotation to specify ordering, and we'd like to use standard TestNG features as far as possible.
The TestNG docs propose using preserve-order to order tests. That looks promising, but only works if you list every test method separately, which seems redundant and hard to maintain.
Is there a better way to achieve this?
I am also open for any other suggestions on how to handle tests that build on each other, without having to impose a total order on all tests.
PS
alanning's answer points out that we could simply keep all tests independent by doing the necessary setup inside each test. That is in principle a good idea (and some tests do this), however sometimes we need to test a complete workflow, with each step depending on all previous steps (as in my example). To do that with "independent" tests would mean running the same multi-step setup over and over, and that would make our already slow tests even slower. Instead of three tests doing:
Test 1: login to application
Test 2: enter some data
Test 3: edit the data
we would get
Test 1: login to application
Test 2: login to application, enter some data
Test 3: login to application, enter some data, edit the data
etc.
In addition to needlessly increasing testing time, this also feels unnatural - it should be possible to model a workflow as a series of tests.
If there's no other way, this is probably how we'll do it, but we are looking for a better solution, without repeating the same setup calls.
You are mixing "functionality" and "test". Separating them will solve your problem.
For example, create a helper class/method that executes the steps to log in, then call that class/method in your Login test and all other tests that require the user to be logged in.
Your other tests do not actually need to rely on your Login "Test", just the login class/method.
If later back-end modifications introduce a bug in the login process, all of the tests which rely on the Login helper class/method will still fail as expected.
Update:
Turns out this already has a name, the Page Object pattern. Here is a page with Java examples of using this pattern:
http://code.google.com/p/selenium/wiki/PageObjects
Try with depends on group along with depends on method. Add all methods in same class in one group.
For example
#Test(groups={"cls1","other"})
public void cls1test1(){
}
#Test(groups={"cls1","other"}, dependsOnMethods="cls1test1", alwaysrun=true)
public void cls1test2(){
}
In class 2
#Test(groups={"cls2","other"}, dependsOnGroups="cls1", alwaysrun=true)
public void cls2test1(){
}
#Test(groups={"cls2","other"}, dependsOnMethods="cls2test1", dependsOnGroups="cls1", alwaysrun=true)
public void cls2test2(){
}
There is an easy (whilst hacky) workaround for this if you are comfortable with your first approach:
At first we just put tests that belong together into one class, and used dependsOnMethods to make them run in the right order. This used to work in TestNG V5, but in V6 TestNG will sometimes interleave tests from different classes (while respecting the ordering imposed by dependsOnMethods). There does not seem to be a way to tell TestNG "Always run tests from one class together".
We had a similar problem: we need our tests to be run class-wise because we couldn't guarantee the test classes not interfering with each other.
This is what we did:
Put a
#Test( dependsOnGroups= { "dummyGroupToMakeTestNGTreatThisAsDependentClass" } )
Annotation on an Abstract Test Class or Interface that all your Tests inherit from.
This will put all your methods in the "first group" (group as described in this paragraph, not TestNG-groups). Inside the groups the ordering is class-wise.
Thanks to Cedric Beust, he provided a very quick answer for this.
Edit:
The group dummyGroupToMakeTestNGTreatThisAsDependentClass actually has to exist, but you can just add a dummy test case for that purpose..
