Annotations¶
Annotations are used to configure tests and suites in a declarative way similar to modern OOP languages. This way, test configuration is stored along with the test logic inside the test package. No configuration files or tables are needed. The annotations names are based on popular testing frameworks such as jUnit. The framework runner searches for all the suitable annotated packages, automatically configures suites, forms suites hierarchy, executes it and reports results in specified formats.
Annotations are interpreted only in package specification and are case-insensitive. It is recommended however, to use the lower-case annotations as described in documentation.
There are two places where annotations may appear:
- at the beginning of the package specification (
%suite
,%suitepath
etc) - right before a procedure (
%test
,%beforeall
,%beforeeach
etc).
Package level annotations need to be separated by at least one empty line from the underlying procedure annotations.
Procedure annotations are defined right before the procedure they reference, no empty lines are allowed.
If a package specification contains %suite
annotation, it is treated as a test package and processed by the framework.
Some annotations accept parameters like %suite
, %test
%displayname
. The parameters for annotations need to be placed in brackets. Values for parameters should be provided without any quotation marks.
Example of annotated test package¶
create or replace package test_pkg is
-- %suite(Name of suite)
-- %suitepath(all.globaltests)
-- %beforeall
procedure global_setup;
-- %afterall
procedure global_cleanup;
/* Such comments are allowed */
-- %test
-- %displayname(Name of a test)
procedure some_test;
-- %test(Name of another test)
-- %beforetest(setup_another_test)
-- %aftertest(cleanup_another_test)
procedure another_test;
-- %test
-- %displayname(Name of test)
-- %disabled
procedure disabled_test;
-- %test(Name of test)
-- %rollback(manual)
procedure no_transaction_control_test;
procedure setup_another_test;
procedure cleanup_another_test;
-- %beforeeach
procedure test_setup;
-- %aftereach
procedure test_cleanup;
end test_pkg;
Supported annotations¶
Annotation | Level | Description |
---|---|---|
%suite(<description>) |
Package | Mandatory. Marks package as a test suite. Optional suite description can be provided (see displayname ). |
%suitepath(<path>) |
Package | Similar to java package. The annotation allows logical grouping of suites into hierarchies. |
%displayname(<description>) |
Package/procedure | Human-readable and meaningful description of a suite/test. %displayname(Name of the suite/test) . The annotation is provided for flexibility and convenience only. It has exactly the same meaning as <descriotion> in test and suite annotations. If description is provided using both suite /test and displayname , then the one defined as last takes precedence. |
%test(<description>) |
Procedure | Denotes that the annotated procedure is a unit test procedure. Optional test description can by provided (see displayname ). |
%beforeall |
Procedure | Denotes that the annotated procedure should be executed once before all elements of the suite. |
%afterall |
Procedure | Denotes that the annotated procedure should be executed once after all elements of the suite. |
%beforeeach |
Procedure | Denotes that the annotated procedure should be executed before each %test procedure in the suite. |
%aftereach |
Procedure | Denotes that the annotated procedure should be executed after each %test procedure in the suite. |
%beforetest(<procedure_name>) |
Procedure | Denotes that mentioned procedure should be executed before the annotated %test procedure. |
%aftertest(<procedure_name>) |
Procedure | Denotes that mentioned procedure should be executed after the annotated %test procedure. |
%rollback(<type>) |
Package/procedure | Defines transaction control. Supported values: auto (default) - A savepoint is created before invocation of each "before block" is and a rollback to specific savepoint is issued after each "after" block; manual - rollback is never issued automatically. Property can be overridden for child element (test in suite) |
%disabled |
Package/procedure | Used to disable a suite or a test. Disabled suites/tests do not get executed, they are however marked and reported as disabled in a test run. |
Suitepath concept¶
It is very likely that the application for which you are going to introduce tests consists of many different packages or procedures/functions. Usually procedures can be logically grouped inside a package, there also might be several logical groups of procedure in a single package or even packages themselves might relate to a common module.
Lets say you have a complex insurance application the operates with policies, claims and payments. The payment module contains several packages for payment recognition, charging, planning etc. The payment recognition module among others contains a complex recognize_payment
procedure that associates received money to the policies.
If you want to create tests for your application it is recommended to structure your tests similarly to the logical structure of you application. So you end up with something like: * Integration tests * Policy tests * Claim tests * Payment tests * Payments recognition * Payments set off * Payouts
The %suitepath
annotation is used for such grouping. Even though test packages are defined in a flat structure the %suitepath
is used by the framework to form a hierarchical structure of them. Your payments recognition test package might look like:
create or replace package test_payment_recognition as
-- %suite(Payment recognition tests)
-- %suitepath(payments)
-- %test(Recognize payment by policy number)
procedure test_recognize_by_num;
-- %test
-- %displayname(Recognize payment by payment purpose)
procedure test_recognize_by_purpose;
-- %test(Recognize payment by customer)
procedure test_recognize_by_customer;
end test_payment_recognition;
And payments set off test package:
create or replace package test_payment_set_off as
-- %suite(Payment set off tests)
-- %suitepath(payments)
-- %test(Set off creation test)
procedure test_create_set_off;
-- %test
-- %displayname(Set off annulation test)
procedure test_annulate_set_off;
end test_payment_set_off;
When you execute tests for your application, the framework constructs test suite for each test package. Then in combines suites into grouping suites by the %suitepath
annotation value so that the fully qualified path to the recognize_by_num
procedure is USER:payments.test_payment_recognition.test_recognize_by_num
. If any of its expectations fails then the test is marked as failed, also the test_payment_recognition
suite, the parent suite payments
and the whole run is marked as failed.
The test report indicates which expectation has failed on the payments module. The payments recognition submodule is causing the failure as recognize_by_num
has is not meeting the expectations of the test. Grouping tests into modules and submodules using the %suitepath
annotation allows you to logically organize your projects flat structure of packages int functional groups.
Additional advantage of such grouping is the fact that every element level of the grouping can be an actual unit test package containing module level common setup for all of the submodules. So in addition to the packages mentioned above you could have following package.
create or replace package payments as
-- %suite(Payments)
-- %beforeall
procedure set_common_payments_data;
-- %afterall
procedure reset_common_paymnets_data;
end payments;
%suitepath
can be provided in tree ways:
* schema - execute all test in the schema
* [schema]:suite1[.suite2][.suite3]...[.procedure] - execute all tests in all suites from suite1[.suite2][.suite3]...[.procedure] path. If schema is not provided, then current schema is used. Example: :all.rooms_tests
.
* [schema.]package[.procedure] - execute all tests in the test package provided. The whole hierarchy of suites in the schema is build before, all before/after hooks of partn suites for th provided suite package are executed as well. Example: tests.test_contact.test_last_name_validator
or simply test_contact.test_last_name_validator
if tests
is the current schema.
Using automatic rollbacks in tests¶
By default, changes performed by every setup, cleanup and test procedure is isolated using savepoint. This solution is suitable for use-cases, where the code that is getting tested as well as the unit tests themselves do not use transaction control (commit/rollback) or DDL commands.
In general, your unit tests should not use transaction control as long as the code you are testing is not using it too. Keeping the transactions uncommitted allows your changes to be isolated and the execution of tests is not impacting others that might be using a shared development database.
If you are in situation, where the code you are testing, is using transaction control (common case with ETL code), then your tests probably should not use the default automatic transaction control.
In that case use the annotation -- %rollback(manual)
on the suite level to disable automatic transaction control for entire suite.
If you are using nested suites, you need to make sure that the entire suite all the way to the root is using manual transaction control.
It is possible with utPLSQL to change the transaction control on individual suites or tests that are part of complex suite. It is strongly recommended not to have mixed transaction control in suite. Mixed transaction control settings will not work properly when your suites are using shared setup/cleanup with beforeall, afterall, beforeeach or aftereach annotations. Your suite will most probably fail with error or warning on execution. Some of the automatic rollbacks will most probably fail to execute depending on the configuration you have.
In some cases it is needed to perform DDL as part of setup or cleanup for the tests.
It is recommended to move such DDL statements to a procedure with pragma autonomous_transaction
to eliminate implicit commit in the main session that is executing all your tests.
Doing so, allows your test to use automatic transaction control of the framework and release you from the burden of manual cleanup of data that was created or modified by test execution.
When you are running test of code that is performing an explicit or implicit commit, you may set the test procedure to run in autonomous transaction with pragma autonomous_transaction
.
Keep in mind, that when your tests runs in autonomous transaction it will not see the data prepared in setup procedure unless the setup procedure committed the changes.
Order of execution¶
When processing the test suite test_pkg
defined in Example of annotated test package, the execution will be done in the following order.
create a savepoint 'beforeall'
execute global_setup
create savepoint 'beforeeach'
execute test_setup
execute some_test
execute test_cleanup
rollback to savepoint 'beforeeach'
create savepoint 'beforeeach'
execute test_setup
execute setup_anotrher_test
execute another_test
execute cleanup_another_test
execute test_cleanup
rollback to savepoint 'beforeeach'
mark disabled_test as disabled
execute test_setup
execute no_transaction_control_test
execute test_cleanup
execute global_cleanup
rollback to savepoint 'beforeall'
