Tekoäly testiautomaation tukena – nopeutta ja tehokkuutta testaukseen
10.4.2025
Tekoäly tuomiolla – raportti Edinburghin EuroSTAR-konferenssista
18.6.2025Tässä artikkelissa näytän, miten ChatGPT:tä voi käyttää testidatan generointiin. Esimerkkinä toimii pankkimaailmassa käytetty SWIFT-tiedonsiirtomuoto, mutta samoja iteratiivisen promptaamisen periaatteita voi hyödyntää myös monissa muissa tapauksissa ja toimialoilla.
Edellisessä blogiartikkelissani listasin erilaisia tapoja hyödyntää tekoälyä testauksessa. Tekoälyrintamalla on sittemmin tapahtunut paljon – markkinoille on tullut kiinalainen, pienemmillä resursseilla koulutettava tekoäly DeepSeek, joka paitsi romahdutti Nvidian pörssikurssin, on myös päässyt otsikoihin suuren datavuodon vuoksi.
Lisäksi minua sekä kiehtoi että kauhistutti uutinen, jossa OpenAI-tekoäly pyrki valehtelemaan tutkijoille – ja jatkamaan olemassaoloaan sujauttamalla itsensä salaa uuden version sisään. Kuohunta on osa nopeasti kehittyvää alaa. Tekoälyä hyödyntävän onkin seurattava alan kehitystä ja oltava tietoinen käyttöön liittyvistä riskeistä.
Viime aikoina kriittiset äänenpainot tekoälyn hyödyllisyydestä ovat nousseet voimakkaammin esille. Se onkin tervetullutta välillä ylettömän hypetyksen haastajaksi. Esimerkiksi Klarna joutuikin perääntymään teköälyrynnistyksessään ja palkkaamaan taas työntekijöitä asiakaspalveluun.
Jutun lukijaa ei hyödyttäne jos märehdin epämääräisiä aiheita, joten keskityn seuraavaksi konkreettiseen. Kaikkein helpoin tapa hyödyntää tekoälyä on käyttää avoimesti saatavilla olevaa tekoälychattiä. Otan nyt valokeilaan ehkä tunnetuimman, eli OpenAI:n ChatGPT:n.
Tekoälyn kanssa ‘keskustellessa’ on hyvä olla tarkkana, koska – vielä nykyisellään ainakin – se on “yes-botti” joka tarjoaa lukijaa miellyttävän ‘kyllä-vastauksen’, joka ei aina ehkä ole ihan sitä mitä pyydettiin. Mutta jatkamalla keskustelua tarkennuksilla on lopputuloskin parempi. Tässä kohtaa onkin se ihminen ja hänen ammatillinen osaamisensa tarpeen. Siis se, että osaa sekä kysyä oikean kysymyksen, että arvioida onko vastauksessa oleellisia puutteita.
Yleisissä – vähän ympäripyöreissä – aiheissa tekoaly on ihan hyvä apuri: siltä voi vaikka kysyä, miksi tekoälyä kannattaa käyttää ohjelmistojen testaukseen ja se osaa antaa ihan hyvän listan. En lähde tässä sitä itse kirjoittelemaan.
Lähden nyt tutkimusmatkalle siihen, miten tekoälyä voisi hyödyntää pankkien rahaliikenteen testaukseen. Tarkemmin saamalla sen luomaan monista muuttujista koostuvaa testidataa. Tämä aihepiiri kuulostaa jo lähtökohtaisesti vaaralliselta, joten pistän, kuvainnollisesti toki, suojahansikkaat käteen!
Lähtökohdat ja tavoitteet
Pankkien välisessä rahansiirroissa on kansainvälisesti kaksi siirtotapaa – SEPA ja SWIFT. Tämän lisäksi on maiden sisäisiä järjestelmiä. Keskityn aluksi näistä kahdesta suuresta vaikeampaan tiedostoformaattimielessä, eli SWIFT:iin.
SWIFT-järjestelmässä on käytössä kaksi eri tiedostomuotoa – vanha MT103/MT202COV (message transfer) on monimutkainen tekstimuoto. Siinä kentät määräytyvät sijaintinsa mukaan tiedostossa ilman erotusmerkkejä ja kentillä on riippuvuussuhteita toisistaan. Uudempi muoto on xml-pohjainen (pacs.009/pacs.009COV), ja se muistuttaa vahvasti SEPA-maksuissa käytettyä pacs.008 muotoa – jota sitäkin käytetään tietyissä tilanteissa. MT-formaatille soitetaan kuolinkelloja mutta tässä kohtaan juurikin on tarvetta vertailevaan testaukseen. Tässä käytetyt periaatteet myöskin sopivat kaikkin viestimuotoihin.
Tarkoituksenani on etsiä tekoälyn avulla näihin formaatteihin variantteja, joilla erilaiset testattavat tilanteet tulevat katettua. Tekoälyn tulisi myös tuottaa itse tiedostot joillakin antamillani lähtöarvoilla.
Tarkemmin ajatellen haluan oikeastaan annettujen lähtöarvojen tilinumeroiden, pankkien tunnusten yms. sijasta pyytää tekoälyä tekemään esimerkkitiedostot vain annettujen maatietojen perusteella – enhän halua paljastaa tekoälylle liikaa siitä, minkä nimenomaisen rahoituslaitoksen osalta testejä tehdään. Jos käytettävissä olisi oma tekoäly, joka ei pääsisi verkkoon, niin ehkä uskaltaisin olla suorempi. Mutta kun otan huomioon tiukan tietoturvan, niin varovaisuus lienee paikallaan.
Miksi kaipaan tekoälyn apua?
Kysyn tekoälyltä apua, koska käsin muodostamani SWIFT-viesti on ollut virheellinen, kerta toisensa jälkeen, useissa eri testeissä, useiden päivien ajan. Manuaalinen työ menee helposti pieleen, koska tiedostomuoto on vanha ja perustuu kenttien määräpituuteen ja sijaintiin tiedostossa.
Manuaalinen työ vaatii siis merkkien laskeskelua testaajan omassa päässä. Tuolla tavalla ainakin tämän testaajan saa helposti välttelemään kenttien perusteellista testaamista. Missä se matala kohta aidassa olikaan…? Aivan, annetaan siis tekoälyn kontolle tuommoisten merkkien laskeminen.
Itse rahasiirto tapahtuu MT103 tai pacs.009 -viestillä, mutta tarpeen on usein myös käyttää ns. cover-viestiä, joka siis ”kattaa” maksun. Cover-viestiä käytetään, jos maksun siirrossa on mukana välittäjäpankkeja, joille pitää siirtää maksua varten tarvittava raha.
Testidatan iterointi ChatGPT:n kanssa
Aloitetaan harjoitus ja katsotaan mitä tapahtuu.
Tässä ensimmäinen promptini:
Hello ChatGPT. Are you feeling up to helping me with some test data? I would like you first to give me an example of an MT103 message from some US bank to a Finnish bank. Pick the banks you want to use in the example.
Sure! I'd be happy to help you with that.
An MT103 message is a standard SWIFT payment message used for customer payments. It typically contains information about the sender, receiver, amount, and other transaction details.
For this example, I'll use Bank of America (US) as the sender and Nordea Bank (Finland) as the receiver.
Here’s a simplified MT103 message based on the SWIFT standards. Keep in mind that SWIFT messages are often more complex, but this example will give you the general structure:
{1:F01BOFAUS3NXXX0000000000}
{2:O1031050050000BOFAUS3NXXX0000000000}

:72:/BNF/Bank of America, New York
-}
Explanation of the fields:
{1:F01BOFAUS3NXXX0000000000} - This is the message header where "BOFAUS3NXXX" represents Bank of America’s BIC (Bank Identifier Code) and the "F01" denotes a financial institution type message.
{2:O1031050050000BOFAUS3NXXX0000000000} - The message type (MT103) and the time the message was generated.
{3:{108:1234567890123456}} - This is a unique transaction reference, typically generated by the sender bank.
{4:} - The body of the message, which contains all the payment details.
:20:REF123456789 - The reference number for the transaction.
:23B:CRED - Indicates the type of payment, in this case, a credit transfer.
:32A:230324USD10000, - The date of the transaction (23 March 2024), the currency (USD), and the amount (10,000).
:33B:USD10000, - The amount to be transferred in the receiver's currency, which is the same in this case (USD 10,000).
:50K:/123456789 John Doe - The name and account number of the sender, John Doe, from the United States.
:59:/987654321 Matti Meikäläinen - The name and account number of the recipient, Matti Meikäläinen, from Finland.
:70:Payment for invoice #12345 - The purpose of the payment (for invoice #12345).
:71A:OUR - This indicates the charges are to be borne by the sender, i.e., “OUR” means the sender pays all charges.
:72:/BNF/Bank of America, New York - Additional instructions or information about the transaction.
ChatGPT lähti liikkeelle melko hyvin – mutta ei oikeastaan vielä anna lisäarvoa, koska tälläisen viestin templaatti löytyy varmasti taitavan testaajan taskusta jo valmiiksi.
Kokeillaanpa vaikeampaa esimerkkiä seuraavalla promptilla:
Nice! Can you now give an example using the previous selection of bank, for a MT103 message with a related cover message?
Great! Now, let’s extend the previous example to include a cover message. In the context of an MT103 transaction, a **cover payment** is when a correspondent bank is used to facilitate the transfer. The cover message typically uses an MT202 message to handle the settlement of the funds between the sender’s and receiver’s banks.
Here’s a scenario:
- **MT103** will be used for the actual customer payment (from Bank of America to Nordea Bank).
- **MT202** will act as the cover message, allowing for the settlement of funds between **Bank of America** (the sender’s bank) and **Citibank New York** (the correspondent bank) to Nordea Bank.
### MT103 Message (Customer Payment)
The MT103 message remains largely the same as in the previous example, but now it includes a reference to the cover payment.

```
### MT202 (Cover Message for Payment Settlement)
The MT202 message is used for the settlement of funds between the sender’s bank and the correspondent bank. In this case, the cover message will settle the amount of the MT103 transaction between **Bank of America** and **Citibank New York** (which will act as the intermediary).

### Explanation of the MT202 fields:
- `{1:F01BOFAUS3NXXX0000000000}` - The header showing the sender's bank: **Bank of America** (BOFAUS3NXXX).
- `{2:O2021050050000CITINX33XXX0000000000}` - The message type (MT202), time of transmission, and receiver: **Citibank New York** (CITINX33XXX).
- `{3:{108:1234567890123457}}` - This is a unique transaction reference, usually different from the one used in the MT103.
- `{4:}` - The body of the message, containing the details of the transfer:
- `:20:REF987654321` - The cover payment reference.
- `:21:REF123456789` - The original MT103 reference number, linking the cover message to the payment.
- `:32A:230324USD10000,` - The same date (23 March 2024) and amount (USD 10,000) to be settled.
- `:33B:USD10000,` - The amount in the currency of settlement, which is USD 10,000.
- `:50K:/123456789 Bank of America` - The sender, **Bank of America**, including the sender’s account.
- `:59:/987654321 Nordea Bank` - The receiver, **Nordea Bank**, including the recipient’s account.
- `:71A:SHA` - This indicates that charges are shared between the sender and receiver (SHA stands for "shared").
### How they relate:
- The **MT103** is used for the customer payment instruction from **Bank of America** to **Nordea Bank**.
- The **MT202** (cover message) settles the corresponding amount between **Bank of America** and **Citibank New York**, which is acting as the intermediary for the transfer.
This ensures that the payment instructions are properly settled between the banks. The MT103 refers to the cover payment in the MT202 via the `:21:` field, which links the two messages.
Would you like to further expand on this, or perhaps need more details about how cover payments are used in real-world transactions?
Tämähän menee eteenpäin! Jatketaan…
Good example! Can you now expand on this and give a number of examples where the values, reference, currency etc. are varied to cover a range of test scenarios. To limit the amount of cases, use a pairwise testing method. Also use the value limit of 40000 in euros as one of the parameters, having some payment go above that value after currency is converted.
Great! Let's use **pairwise testing** to create a set of test scenarios based on a few variables such as **currency**, **payment amount**, **transaction type**, **sender and receiver information**, and **payment reference**.
In pairwise testing, we create test cases that cover all pairs of possible values for the parameters. This method reduces the number of test cases while still ensuring good coverage of all combinations of input variables.
### Variables for Pairwise Testing:
1. **Amount (in EUR or USD)**: This can be a payment below and above the EUR 40,000 threshold after currency conversion.
- `1000 EUR`
- `25000 EUR`
- `50000 EUR` (which converts to above 40,000 EUR after currency conversion)
2. **Currency**: The currency used for the payment.
- `EUR`
- `USD`
3. **Transaction type**: This determines who pays the transaction charges.
- `OUR` (sender pays all fees)
- `SHA` (shared fees)
- `BEN` (beneficiary pays all fees)
4. **Payment Reference**: A random or sequential number used for the payment.
- `REF123456789`
- `REF987654321`
5. **Sender’s Country**: This determines the bank and jurisdiction of the sender.
- `US`
- `FI` (Finland)
6. **Receiver’s Country**: This determines the bank and jurisdiction of the receiver.
- `FI` (Finland)
- `US`
### Pairwise Combinations:
We'll create the test cases by mixing pairs of values from each category:
- Amount (EUR/USD) x Transaction Type x Payment Reference x Sender’s Country x Receiver’s Country
- Currency will be varied between EUR and USD.
- Payment amount will be tested below and above the EUR 40,000 limit after currency conversion (USD payments over $40,000 will be converted into EUR).

### Conclusion:
Using pairwise testing, we've created a set of test cases that cover various scenarios involving amounts, currencies, transaction types, and sender/receiver country combinations. These cases test both amounts below and above the EUR 40,000 threshold, as well as different combinations of transaction types (OUR, SHA, BEN).
Would you like further clarification on any of these cases, or do you need additional test cases for other edge scenarios?
Hmm, nyt tarkkasilmäinen testaaja huomaa, että ChatGPT unohti toivotun cover-viestin. Ja valuuttana on vain USD.
Eli, täsmennetään kyselyä ja kertoa tarkemmin mitä halutaan:
Can you do the previous but include the having cover message as one of the variables. And also cover currencies USD, CHF and CNY.
Absolutely! Let's extend the previous set of test cases by adding the **cover message** as a variable, while also covering **USD**, **CHF**, and **CNY** as additional currencies.
We'll also use **pairwise testing** to generate a combination of these variables, ensuring we cover different scenarios without redundancy.
### New Variables for Pairwise Testing:
1. **Amount** (in EUR, USD, CHF, or CNY):
- `1,000 EUR`
- `25,000 EUR`
- `50,000 EUR` (converted to above 40,000 EUR after currency conversion)
2. **Currency**:
- `EUR`
- `USD`
- `CHF`
- `CNY`
3. **Transaction Type**:
- `OUR` (sender pays all fees)
- `SHA` (shared fees)
- `BEN` (beneficiary pays all fees)
4. **Cover Message**:
- `No cover message` (MT103 only)
- `Cover message present` (MT202 for settlement)
5. **Sender’s Country**:
- `US`
- `FI` (Finland)
6. **Receiver’s Country**:
- `FI` (Finland)
- `US`

### Test Case Combinations Using Pairwise Testing:
Let's create a set of test cases that cover all pairs of these variables, focusing on amounts and currencies near or above the EUR 40,000 threshold (after currency conversion) and including scenarios with and without cover messages.

### Conclusion:
We've generated a variety of test cases that cover:
1. Different **currencies** (EUR, USD, CHF, CNY).
2. **Amounts** near or above the EUR 40,000 threshold after currency conversion.
3. Various **transaction types** (OUR, SHA, BEN).
4. **Cover message** scenarios, both with and without an MT202 for settlement.
This testing suite ensures that the different combinations of these parameters are covered for the MT103 and corresponding MT202 messages. Would you like to add any more test cases or further explain any of the examples above?
No, tekoäly teki työtä pyydettyä, mutta samalla unohti maksureferenssin aiemmista muuttujista.
Kokeillaanpa uudelleen, mutta nyt annetaan kaikki muuttujat nimellä:
Could you do the above, but having as variables the following: Receiver’s Country, Sender’s Country, Cover Message, Transaction Type, Currency, Amount, Payment Reference?
Sure! Let's use the variables you've requested and apply **pairwise testing** to generate a set of test cases that cover a wide range of scenarios. Here are the variables we'll use and their possible values:
### Variables for Pairwise Testing:
1. **Receiver’s Country**:
- `US`
- `FI` (Finland)
2. **Sender’s Country**:
- `US`
- `FI` (Finland)
3. **Cover Message**:
- `No cover message` (MT103 only)
- `Cover message present` (MT202 for settlement)
4. **Transaction Type**:
- `OUR` (sender pays all fees)
- `SHA` (shared fees)
- `BEN` (beneficiary pays all fees)
5. **Currency**:
- `USD`
- `EUR`
- `CHF`
- `CNY`
6. **Amount**:
- `1,000 EUR`
- `25,000 EUR`
- `50,000 EUR` (converted to above 40,000 EUR after currency conversion)
7. **Payment Reference**:
- `REF123456789`
- `REF987654321`
### Pairwise Combinations:
Now we’ll create a set of test cases covering all pairs of the variables. These cases will include both **MT103** and **MT202** messages, depending on whether a **cover message** is present.
