Testing web services is very important part of integration testing on web projects. In this presentation you can learn the best approaches, tools and features of Web Services testing. Soon I'll share url with a video from my presentation.

1. Testing web
services

2. About Me

3. Taras Lytvyn

4. Prehistory

5. Service =
web interface
+
Web service on Java
+
DB usage

6. SERVICE AS STATE
MACHINE

7. Google services

8. Web Services

9. What is web service ?
QA point of view

10. Examples

11. You can find web services in Network tab

12. Classification

13. RES SOAP
T

14. 1. Give every “thing” an ID
REST 2. Link things together
3. Use standard methods
Representational
4. Resources can have multiple
State Transfer representations
5. Communicate independently

15. 1. Use WSDL for description
SOAP 2. SOAP is approach of
protocols and standards
Simple Object
3. Works with operations
Access Protocol

16. WSDL
Web Services Description
Language is an XML-based
interface description language
that is used for describing the
functionality offered by a web
service.

17. Request methods

19. Content Type on
response

20. So what to test ?

21. Response Correctness
data data data fullness
type order

22. What else ?

23. • client part that uses this service
• http statuses
• authorization
• response timeout
• load testing
• security testing
• NEGATIVE cases !

24. REAL EXAMPLE
GET
http://maps.googleapis.com/maps/api/elevation/json?
locations=39.7391536, -104.9847034|36.455556, -116.866667
&sensor=true
Valid HTTP status code – 200 OK
Response timeout !>= 0.5 s
Negative cases (check status):
- incorrect locations
- incorrect sensor value

25. {
"results": [
{
"elevation": 1608.637939453125,
"location": {
"lat": 39.7391536,
"lng": -104.9847034
},
"resolution": 4.771975994110107
},
{
"elevation": -50.78903579711914,
"location": {
"lat": 36.455556,
"lng": -116.866667
},
"resolution": 19.08790397644043
}
],
"status": "OK"
}

26. <Response xmlns="http://maps.googleapis.com/maps/api/elevation/json">
<results>
<e>
<elevation>1608.637939453125</elevation>
<location>
<lat>39.7391536</lat>
<lng>-104.9847034</lng>
</location>
<resolution>4.771975994110107</resolution>
</e>
<e>
<elevation>-50.78903579711914</elevation>
<location>
<lat>36.455556</lat>
<lng>-116.866667</lng>
</location>
<resolution>19.08790397644043</resolution>
</e>
</results>
<status>OK</status>
</Response>

27. So how to test ?

28. TEST WITH:
Service Mocks
Parsing
- xpaths
- regexps
Manually
Automation !!!

29. Testing features...

30. PROBLEMS:
- SERVICE DOCUMENTATION
- DBC
- “DYNAMIC” RESPONSE PROBLEM

31. SERVICE DOCUMENTATION
DOC. example

32. DATA BASE Connection
for reading data

33. “Dynamic” response

34. Tools

35. EXAMPLE:
rem curl -i -H "Content-Type: application/json" -X POST -d
"11032480" http://172.22.40.73:8080/gift-registry/registry-
products/5017a4d3ee12d093a5794968/delete

36. Manual testing

41. SOAP UI
- Support different service standards
- Service mocking
- Groovy & Java API
- Ability of Security and Load Service
Testing
- Logging results
- Maven plugin +
- Could be easily integrated to CI
- Eclipse Plugin
- Test Suite could executed with JUnit

42. SOAP UI PROJECT SAMPLE

43. REAL EXAMPLE
GET
http://maps.googleapis.com/maps/api/elevation/json?
locations=39.7391536, -104.9847034|36.455556, -116.866667
&sensor=true
Valid HTTP status code – 200 OK
Response timeout !>= 0.5 s
Response correctness

45. Response parsing
approach

47. JSON Object Library

48. JACKSON
JSON LIBRARY

49. {
"results": [
{
"elevation": 1608.637939453125,
"location": {
"lat": 39.7391536,
"lng": -104.9847034
},
"resolution": 4.771975994110107
},
{
"elevation": -50.78903579711914,
"location": {
"lat": 36.455556,
"lng": -116.866667
},
"resolution": 19.08790397644043
}
],
"status": "OK"
}

50. fill levelsCorrect

52. Conclusion
SUCCESSFUL WEB SERVICE
TESTING =
SOAP UI + ECLIPSE + JAVA +
JACKSON + SOAP UI JAVA API

53. resolve all needs,
approaches and
problems described
earlier

54. Thank you !
