Test 1: Update database with changeLog in XML format

From the command line in the project directory

mvn package

mvn liquibase:update

Check you database, a new record has been added to pdpstatistics

[INFO] SELECT * FROM DATABASECHANGELOG ORDER BY DATEEXECUTED ASC, ORDEREXECUTED ASC
[INFO] SELECT count(1) FROM information_schema.tables
WHERE table_name = 'PDPSTATISTICS'
[INFO] INSERT INTO PDPSTATISTICS
(ID, NAME, VERSION, PDPGROUPNAME, PDPSUBGROUPNAME, POLICYDEPLOYCOUNT, POLICYDEPLOYFAILCOUNT,
POLICYDEPLOYSUCCESSCOUNT, POLICYEXECUTEDCOUNT, POLICYEXECUTEDFAILCOUNT,
POLICYEXECUTEDSUCCESSCOUNT, TIMESTAMP)
VALUES (3, 'TestName', '1.0.0', 'TestGroup', 'TestSubGroup', 1, 1, 1, 1, 1, 1, now())
[INFO] Custom SQL executed
[INFO] ChangeSet dbchangelog.xml::policy-1::policy ran successfully in 7ms

Test 2: Rollback update

mvn liquibase:rollback -Dliquibase.rollbackCount=1

new record has been removed has been dropped

[INFO] SELECT * FROM DATABASECHANGELOG ORDER BY DATEEXECUTED ASC, ORDEREXECUTED ASC
[INFO] Rolling Back Changeset:dbchangelog.xml::policy-1::policy
[INFO] DELETE FROM PDPSTATISTICS WHERE ID=3
[INFO] DELETE FROM DATABASECHANGELOG WHERE ID = 'policy-1' AND AUTHOR = 'policy' AND FILENAME = 'dbchangelog.xml'

Test 3: Generate database dump chageLog in YAML format

Add the following 2 lines to liquibase.properties

outputChangeLogFile: dbchangelog.mariadb.yaml
diffTypes: catalog,tables,views,columns,indexes,foreignkeys,primarykeys,uniqueconstraints,data,storedprocedure

mvn liquibase:generateChangeLog

The file dbchangelog.mariadb.yaml will contain the DDL for your database in YAML format

Test 4: Generate database dump chageLog in SQL format

change outputChangeLogFile: dbchangelog.mariadb.yaml to outputChangeLogFile: dbchangelog.mariadb.sql

The file dbchangelog.mariadb.sql will contain the DDL for your database in SQL format

Test 5: Update database with changeLog in YAML format

Add dbchangelog.yaml

dbchangelog.yaml

The embedded SQL has been removed from the changeLog and put in separate SQL files.

Common tests used in liquibase are available here: common.tests.changelog.yaml

We can use all the liquibase functions with SQL and include rollback:

dbchangelog-sql10.yaml

databaseChangeLog:
  -  changeSet:  
       id:  policy-26

insert_JpaPdpPolicyDeploymentAudit.sql

insert into JpaPdpPolicyDeploymentAudit (id, name, version, pdpGroup, PdpType, action, timeStamp, changedByUser) values 
(9, 'TestName', '1.0.0', 'TestGroup', 'TestType', 1, now(), 'Admin'),
(10, 'TestName', '1.0.0', 'TestGroup', 'TestType', 1, now(), 'Admin');

rollback_insert_JpaPdpPolicyDeploymentAudit.sql

delete from JpaPdpPolicyDeploymentAudit where id in (9,10);

Important concepts to be considered

Labels and Context - to separate environments and releases
Tags - to set a rollback check point
Prechecks - to check if a particular changeSet needs to be executed
Different formats - decide the best one for the team to work with
Include rollback statement with changeSet to allow user to undo changes.
