unit testing - Manage transactions within a spring transactional test case. -


i have test case insert domain object. within domain object 1 of fields "deploymenttype" if not set postgres has default populate production.

i want test in spring unit test of default set when insert deploymenttype set null , postgres taking care of it.

my test case extends abstracttransactionaltestngspringcontexttests , has been annotated 

@transactional(propagation = propagation.nested) @transactionconfiguration(transactionmanager = "transactionmanager", defaultrollback = true)

the unit test case follows. 

@test public void createcustomerwithsite() {     this.customerservice.createcustomersite(testdata.makecustomersite(this.customer, "test-alias"));      final list<customersite> list = this.customerservice.findcustomersites(this.customer.getid());     assertthat(list.size(), is(1));     final customersite cs = list.get(0);     assertthat(cs.getclusterdeploymenttype(), is(clusterdeploymenttype.production)); }

now since test transactional commit never takes place , hence when domain object see "deploymenttype" null , test fails.

so in such case when want test db behavior in unit test, guess need access transactionmanager in middle of test , commit transaction. start new transaction , domain object db , check if default value has been set db while inserting.

like : 

       this.customerservice.createcustomersite(testdata.makecustomersite(this.customer, "test-alias"));        transactionmanager tm = gettransactionmanager();        tm.commit(); // default type insterted in db , visible in next transaction.        tm.begintransaction();           final list<customersite> list = this.customerservice.findcustomersites(this.customer.getid());         assertthat(list.size(), is(1));         final customersite cs = list.get(0);         assertthat(cs.getclusterdeploymenttype(), is(clusterdeploymenttype.production));

how access transaction manager in unit test transactional. right way ?

you need access entitymanager/sessionfactory (depending on use) , class flush.

then use means of querying database (a jdbctemplate) retrieve row database , check if correct. don't want test same means put in database testing first (or second level) cache way.

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
