Is there a real BENEFIT in SQL * Developer Automated Unit Testing?

I'm trying to understand the unit test in SQL * Developer. Asked me to evaluate it as a method of test automation on an integration solution that we develop.

(1) my 'A' schema has this table:

SQL > DESC EMP

Name                                      Null?    Type

----------------------------------------- -------- --------------------

EMPID NOT NULL NUMBER

EMPNAME VARCHAR2 (30)

SALARY NUMBER (7.2)

COMM_PCT NUMBER (2.2)

Table (2). has these values:

SQL > SELECT * from emps;

EMPID EMPNAME SALARY COMM_PCT

---------- ---------- ---------- ----------

1 ROHAN 10000.05

2 JOHN 20000

3 PETER.06

4 SMITH

(3.) I create this procedure in drive A:

create or replace

PROCEDURE award_bonus (NUMBER, sales_amt NUMBER p_empid)

AS

REAL Commission;

comm_missing EXCEPTION;

BEGIN

SELECT comm_pct IN the commission OF EMP

WHERE empid = p_empid;

IF the commission IS NULL THEN

RAISE comm_missing;

ON THE OTHER

PGE UPDATED

SET salary = salary + sales_amt * commission

WHERE empid = p_empid;

END IF;

END award_bonus;

(4) now, I want to create a unit test in SQL Developer to test this procedure.

(5) I created a user "unit_test_repos" according to the instructions in the tutorial.

(6) ' SELECT OPERATION': I specifies the procedure of award_bonus.

(7) ' SPECIFY the name of test': give a name and select "create with a single model.

(8.) 'SPECIFY the STARTUP': Add a ' copy Table or the line "the startup process.

-I give "EMP" as the source table.

-And then I get this for the 'generated query.

SELECT ROWID AS SRC$ ROWID, s.* FROM EMP s

-Target table has "TMP$ AWARD_BONUS.

(Q1) WHAT IS THE PURPOSE OF CREATING ANOTHER TABLE?

(Q2) WHEN THE TEST IS DONE, ARE ROWS OF PGE copied into this table?

(Q3) Why is this? Why can't the test simply read 'EMP '?

(9) "PARAMETERS SPECIFY": I give "Input".

-1 for P_EMPID

-10000 for SALES_AMT

-In "Expected result", I say "success."

(Q4) So I should know in my mind the results of the proc, foregoing given entries?

(10) ' SPECIFY VALIDATION': I add validation "poll rows of queries.

-I paste the following query: SELECT count (*) FROM EMP WHERE empid = 1 AND salary = 10500

-that is, I know that for an amount of 10000 sales, employee 1 will get a Commission of 10000*.05 = 500. For example, 10000 (its sal) + 500 = 10500.

(Q5) The thought that the above is correct?

(11) "TEARDOOWN SPECIFY": give nothing.

(12) my unit test is created.

(13.) I run now by clicking on the button of the beetle, to the left of the green arrow. Unit test is run.

(14) now in my table a.emps, 1 salary has increased to 10 500, and the diag test case, I get the "execution results: SUCCEED.

(15) now, I run the unit test again.

(16.) salary 'EMP' table emp 1 is passed to 11000 (which is correct) and the so-called execution results "SUCCESS".

(Q6)  My question is: the query I gave for validation, SELECT count (*) FROM EMP WHERE empid = 1 AND = 10500 salary, now gives 0. so, this means that no row is returned for this condition and so the test must FAIL. But how is SQL * Developer said that the test was SUCCESSFUL. How does this system of validation?

(17.) I went through the tutorial, but I do not understand these concepts >

(Q7) What is the purpose of disassembly? I undersand the option 'drop table' "disassembly", where you drop the temporary table, but I do not understand the others, 'Table or line restore' and 'code pl/sql user '?

(Q8) WHAT IS the advantage of making the test like this? Can I use an Excel spreadsheet and make dozens of unit tests faster than this method?  It is easy to understand too. This method is complicated.

Your answers and your advice would be greatly appreciated.

The temporary table to hold the original values for EMP. After the test runs, you must configure the disassembly to reset the return values of the temporary for the next time table that the test works again, he has values of expected start.

  • Developer SQL 3 EA1: Unit Test

    Hello

    I just started to use the work unit test framework in SQL Developer 3 EA 1 and I need assistance, definition of a test case involving parent - child tables that are handled using an API from plsql. The API for the child table requires a registration key in the parent table. The parent record and its key is created by a process of starting test case. The key is retrieved using a query of dynamic value in the implementation of the test. It seems that the dynamic value query is executed before the start of the test case process have been executed. Is this expected behavior? My expectation is that the boot process are executed before the dynamic values query.

    Also, is it possible to use values resulting from processes of startup as the case other than type parameter values by using a dynamic query in value?

    Summary test scenario:

    2 boot process: the first deletes all the data tables parent and the child. The second inserts in a record in the parent table.

    No disassembly process.

    Test implementation: application of dynamic value that selects the key of the parent table and defines literals for the remaining parameters of test cases.

    1 process validation: check if a record has been inserted into the table of childe with expected values.

    Thank you

    Alistair

    Hi Alistair.

    We execute the dynamic query to control how many times the test (start, test cases, validation, demolish) cycle runs.

    To get the behavior you want, put the test in a test suite and test suite start do the initialization of the table for you.

  • Column with the default (to_date()) - failure on SQL Developer

    Hello

    I will you run the following statement:

    ALTER TABLE PERIOD
    ADD
    (
    PP_START_DATE DATE default to_date ('19000101', 'YYYYMMDD') NOT NULL,
    PP_END_DATE DATE default to_date ('19000101', 'YYYYMMDD') NOT NULL
    );

    This works very well and as planned. Existing entries in the table will win by default - that day.

    Now, when I open SQL Developer and go on the columns tab and then click on the small button edit below that an editor window opens showing me all the columns and their specifications.
    Here, I am able to modify change data. I notice that, in the columns of default_value for my two new columns, the value is ' to_date ('19000101', 'YYYYMMDD').

    Well I wonder about this but can SQL Developer, due to the use of a function, knows not what is calculated it and it can depends on somtething like Sysdate so that the SQL Developer must keep this dynamic statement.
    -> Ok so far.
    But when I (no matter if I change something or not) not to click OK, I get an error as follows:

    =========================================================
    Column validation failure
    ---------------------------------------------------------
    Invalid expression ' to_date ('19000101', 'YYYYMMDD').
    DATE or TIMESTAMP expression expected.
    =========================================================

    The question I have is: why is a failure and can do I do something wrong?
    I can still edit the table using SQL, so this isn't the problem. But I wonder if it's an allusion to a bigger mistake.
    If possible: is there a way to get SQL Developer working with it without losing the default dynamic value?

    Thanks for the replies.

    This seems to be the same "not a bug" that has been reported here a few days ago:

  • Oracle SQL Developer 3.1 or 1.5.5 Oracle11g customer?

    Hello

    What SQLdeveloper is the latest version? I just installed a client Oracle11g on Windows XP 32 bit that comes with SQLDeveloper and installs it in ORACLE_HOME. This is the version 1.5.5.
    How is it related to version 3.1? What is the difference?
    The standalone version was 3.0.0x.

    Thank you
    Richard

    3.1 is the latest.

    The reason why the version shipped with 11g is so old, it's that the publication cycle for the DBMS (including the client bundle) is much slower than SQL Developer. GR 11, 2 is a couple of years now and there are several versions of SQL Developer since then.

  • SQL Developer 3.1 Bug: Tabs get closed!

    Hello!

    There is a bug in SQL Developer 3.1 which closes previously opened editors to object when the number of open editors increases over a certain amount.

    for example:
    Open the PL/SQL package editors by clicking on it.
    After a number of open package, the first fork packets begin to disappear.
    When packets of theses have been published, you are asked if you want to save, ignore, or cancel the operation.

    Best regards
    Matthias Schulz

    Hi Matt,

    This isn't a bug. The behavior is controlled through preferences:

    1 PL/SQL Editor: tools | Preferences | Code editor | Auto code Pin (checkbox) + Max Open (input field) PL/SQL publishers.
    2 ObjectViewer: Tools | Preferences | Database | ObjectViewer | Automatically freezing object viewer Windows (check box).
    3 worksheet: tools | Preferences | Database | Worksheet | Close all the worksheets on disconnect (checkbox). Otherwise these are basically open.

    So we have a question of minor terminology in what concerns the "Pin" versus "Freeze". Furthermore, another problem with narrowing width tab as tab number increases:
    Please change the way are managed the tabs in the window

    Kind regards

  • Oracle SQL Developer 3.0: Debugging of PL/SQL anonymous blocks: ISSUES

    Hello
    I just downloaded the Oracle SQL Developer 3.0. I used EA versions because they have emerged and was happy to see the final version. So I immediately tried to debug an anonymous block (something I was not looking to do in EA versions) and nothing happened.

    The "Debug" is grayed out and the string 'ctrl-SHIFT-F10' key did nothing. I found this forum:
    Re: 30EA1: debugging of anonymous block?
    and Vadim Tropashko follow-up advice. This has nothing to my anonymous block but has worked well for a simple example.

    So I started to whittle my anonymous block to the bottom to find the culprit, here's a breaking point repeatable for me:
    declare
    stmt1 long;
    stmt2 long;
    stmt3 long;
    stmt4 long;
    p_data varchar2( 500 );
    i      varchar2( 10 );
BEGIN
    STMT1 := 1;
    STMT2 := 1;
    STMT3 := 1;
    STMT4 := 1;
    
    --the moment this is in the block "Debug" is no longer an option
     select
        SendDocumentResult
       into
        p_data
       from
        XMLTABLE( '/data' 
                PASSING 
                xmltype.createxml( '<?xml version="1.0" encoding="utf-8"?><data><SendDocumentResult>test</SendDocumentResult></data>' ) 
                COLUMNS SendDocumentResult varchar2( 1000 ) PATH 'SendDocumentResult' ) ;
end;
    The moment that I SELECT INTO... XMLTABLE() it fails (a normal SELECT INTO works very well).

    Is this a problem with my environment or there's a problem with SQL Developer 3.0.04. Overlooking the comments of K, it seems that debugging has worked for 'simple' blocks, so I wonder if it's just out of reach...

    My environment:
    Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production     
PL/SQL Release 11.2.0.1.0 - Production

    If you have a user with SYSDBA privileges, then the database management report will display the starting and stopping of the buttons on the database. The stop is the easy part. To start the database from here, you must have configured environment. You must have a static listener configured for the database.

  • PL/SQL, used in application of the APEX of unit tests

    question by my client:

    I develop an Oracle Application Express application and work on unit tests for stored procedures in PL/SQL and the packages that are stored in the underlying database and used by the application of the APEX. These unit tests must run in the context of SQL Developer Unit Test.
    The problem is that the PL/SQL code stored in the database using functions such as NV('APPLICATION_ITEM') to access items in the application of the apex. They do return all values when I try to execute the PL/SQL within the unit test framework, that is to say in the backend. While it is good that the NV is not error, NULL haven't really work well in my scenario either (for example when the result of this function is inserted into a column NOT NULL in a table). I can think of a few workarounds, such as the creation of my own function NV within the schema to test return values desirable, but nothing seems a really satisfactory solution. I wonder if there is no recommendation to Oracle for this scenario - how can I run code that uses the APEX via backend-specific features. I found nothing in the documentation of the APEX for this but I would like to know if there is a recommendation how to better deal with this case.

    I use SQL Developer version 4.0.0.13.80

    Hello

    Indeed, you must set your PL/SQL function calls. This would be the cleanest solution.

    There is an alternative. Please see the following article on the creation of an APEX in PL/SQL session: Martin Giffy D'Souza on Oracle APEX: how to create a Session of the APEX in PL/SQL

    This approach allows to set the values of APEX application item before you run your unit tests. I don't know if it's possible in SQL Developer Unit Test, but it might get you further down the road.

    Good luck

    What is a database of the container

    So, what is the big advantage in this configuration, you may ask? Couldn't we have just created several ordinary vanilla instead of several PDB databases? Yes, we could have; but each of these 'plain vanilla' databases would have then his own load of instance (process and memory). PDB do not have an instance associated with them, eliminating this overload. Let's look at the installer with an example. Suppose you have a CBD (database container - the real database that hosts the other PDB files) called CONA, who has a calledPDB1 of the PDB. If you check the Oracle instance, you will see that there is one - that of the CBD. First, let's check the ORACLE_SID:

    [oracle@prosrv1 ~]$ echo $ORACLE_SID CONA

    That's all. There is only a single SID; not one for each PDB. Then we will check the process, especially very important that known as 'pmon ":

    See this last sentence above? See this line in the status of listening port you have posted?

    Service "Pdb1" has 1 instance (s).

    Pdb1 has a 'service' - a SERVICE_NAME allows to connect to him and all other PDB files.

  • Bug: Details of body inaccurate package SQL Developer 4.0 and 4.1

    I went through the trouble to recompile the schema SYS with native = PLSQL_CODE_TYPE and PLSQL_OPTIMIZE_LEVEL = 3. I found that it was unwise to change the PLSQL_OPTIMIZE_LEVEL for package under SYS specifications, so I left them alone. When I query the view of ALL_PLSQL_OBJECT_SETTINGS, it shows me that my Package body are properly compiled at level 3 and the specs are still 2. However when I look at the Details tab in SQL Developer 4.0 or 4.1 last Early Adopter, it shows the it is PLSQL_OPTIMIZE_LEVEL = 2. I did a test for the PLSQL_CODE_TYPE and the details of body in SQL Developer also follow the specification and not true values. I used the sub query to verify the real compile settings.

    SELECT owner,
